Islam Part 3 — The Assimilation Myth

Series: Know What You Believe and Why — Track 2
The Question Nobody Wants to Ask
There is a question that sits at the center of the Western conversation about Islam that almost nobody in polite company will ask directly. It is not a question about terrorism. It is not a question about whether Muslims are good people. It is a more fundamental question about whether a religious and legal tradition that makes total claims on every aspect of life — law, governance, family structure, the treatment of non-believers — can be absorbed into a pluralistic liberal democracy without fundamental tension.
The answer that Western institutions have largely settled on — that Islam is simply a religion like any other, that its violent expressions are entirely the product of political grievance and economic marginalization, and that integration is proceeding normally — is not supported by the evidence.
This article presents that evidence. Not to generate fear. Not to justify hostility toward individual Muslims. To give Christian men an honest picture of what is happening in Western societies and what it means for the church's engagement with the Muslim world.
What Assimilation Typically Looks Like
When immigrant communities arrive in Western countries, the historical pattern is broadly consistent: the first generation maintains strong ties to the culture of origin, the second generation navigates between two cultures, and the third generation is largely assimilated into the host culture. Language shifts. Cultural practices adapt. Religious observance often moderates.
This pattern has held, with variations, for waves of Catholic, Jewish, Eastern Orthodox, Hindu, and Buddhist immigrants to Western countries. It has not held consistently for Muslim immigrant communities in Western Europe, and the data on why is worth examining honestly.
The European Data
Western Europe has had significant Muslim immigration since the 1960s, primarily from North Africa, Turkey, and South Asia. The communities are now into their second and third generations. The assimilation data is mixed at best and alarming in specific areas.
A 2016 Policy Exchange survey in the United Kingdom found that 23 percent of British Muslims said Sharia law should replace British law in areas with Muslim majorities. A 2016 Channel 4 survey found that 52 percent of British Muslims believed homosexuality should be illegal and 23 percent supported the introduction of Sharia law in Britain.
In France, a 2016 Institut Montaigne study found that approximately 28 percent of French Muslims — roughly 1.5 million people — held what the study described as "totally opposed" values to French republican principles, including support for Sharia over French law and rejection of gender equality.
In Germany, a 2017 study by the Konrad Adenauer Foundation found that 47 percent of young Muslims in Germany placed Islamic law above German law.
These numbers do not represent the majority of Muslims in Western Europe. They represent a significant and, in some surveys, growing minority. And they represent a specific challenge that is different in kind from the challenges posed by other immigrant communities: a portion of the Muslim population that does not regard the host country's legal and social framework as legitimate and that regards its own religious law as superseding it.
The Radicalization Question
The relationship between mainstream Islamic theology and violent extremism is a question that Western governments, academics, and Muslim communities have debated intensely since September 11, 2001. The dominant Western institutional position has been that terrorism has nothing to do with Islam — that it is entirely the product of political grievance, economic marginalization, and the manipulation of religion by bad actors.
This position is not supported by the evidence, and a growing number of Muslim reformers — people like Maajid Nawaz, Ayaan Hirsi Ali, and Irshad Manji — have said so publicly at considerable personal risk.
The connection between mainstream Islamic theology and violent extremism is not that most Muslims are violent. They are not. It is that the theological resources for justifying violence against non-Muslims exist within the tradition, are acknowledged by mainstream Islamic scholars, and are drawn upon by extremists who are not, in most cases, misreading the texts. They are reading specific texts — the Verse of the Sword, the hadith on apostasy, the jurisprudence on jihad — and applying them with a consistency that mainstream Muslims reject but cannot always refute on purely textual grounds.
Maajid Nawaz, a former Islamist who became a counter-extremism activist, has described this as the challenge of Islamism — the political ideology that seeks to impose Islamic law on society — which he distinguishes from Islam as a personal faith. His argument is that Islamism is a modern political ideology that uses Islamic texts selectively, but that the texts it uses are real and that the Muslim community has a responsibility to develop a robust theological counter-narrative. That counter-narrative, he argues, does not yet exist at sufficient scale.
What This Means for the Church
The church's response to the Muslim world in the West has two failure modes. The first is hostility — treating every Muslim as a threat, refusing engagement, and allowing fear to replace the gospel imperative. This is a failure of both courage and theology. The gospel is for every person. The command to make disciples of all nations does not have an asterisk next to Islam.
The second failure mode is naivety — pretending that the theological and political challenges posed by classical Islam are not real, that all religious traditions are equally compatible with Western pluralism, and that honest engagement with the difficult parts of Islamic teaching is somehow unkind to Muslim people. This is a failure of both honesty and love. You cannot love someone into the truth by pretending the truth is not what it is.
The church's calling is neither hostility nor naivety. It is honest, courageous, compassionate engagement — with the texts, with the data, and with the people.
The Gospel Opportunity
Here is what the data also shows, and what rarely gets discussed: Muslims are coming to faith in Jesus Christ in significant numbers. Estimates of Muslim-background believers worldwide range from hundreds of thousands to several million, with the highest concentrations in Iran, Algeria, and Indonesia. The Iranian church — largely underground, largely Muslim-background — is one of the fastest-growing Christian communities on earth.
The testimonies of Muslim-background believers consistently emphasize two things: dreams and visions of Jesus, and Christians who were willing to have honest, respectful conversations about who Jesus actually is. Not Christians who pretended the differences did not exist. Christians who knew what they believed, could articulate it clearly, and engaged with genuine love and genuine conviction.
That is the model. Not the crusade. Not the interfaith dialogue that papers over the differences. The honest conversation between people who take truth seriously enough to disagree about it and love each other enough to keep talking.
Practical Applications
Know the data. The Pew surveys, the Policy Exchange surveys, the Institut Montaigne study — these are publicly available. Read them. Form your own informed view. Do not rely on either the media narrative that everything is fine or the political narrative that everything is a crisis.
Distinguish between Muslims and Islamism. The Muslim man who lives next door, coaches his kid's soccer team, and has never thought about Sharia law is not the same as the political ideology that seeks to impose Islamic governance on Western societies. Treat people as individuals. Engage ideologies as ideologies.
Support Muslim-background believers. People who leave Islam for Christianity face real consequences — family rejection, social ostracism, and in some contexts, genuine physical danger. The church's responsibility to these brothers and sisters is significant and largely unmet. Find out what organizations are supporting them and get involved.
Have the conversation. The Muslim population in Western countries is not going to decrease. The church's options are engagement or irrelevance. Engagement requires knowing what you believe, knowing what Islam teaches, and being willing to have honest conversations that do not pretend the differences are smaller than they are.
The Closing Charge
The assimilation myth is the comfortable story that says Islam in the West is proceeding like every other immigrant religious tradition — that the second and third generations will moderate, that the theological tensions will resolve themselves, that patience and tolerance are sufficient responses.
The data does not support that story. The theological tradition does not support that story. The experience of Western European societies that are a generation ahead of the United States in this process does not support that story.
What the data does support is this: there are millions of Muslims in Western countries who are asking the same questions every human being asks — about meaning, about God, about what happens when they die. Many of them have never had an honest conversation with a Christian who knew what they believed and why. Many of them are one conversation away from a question that could change everything.
The church has the answer. The question is whether it has the courage and the preparation to give it.
That is what this series has been building toward. Know what you believe. Know why you believe it. Know what the alternatives actually teach. And then go have the conversation.
