This is a really good post and I agree, however I think your treatment of France (and Belgium) is a bit facile, since the claim of “high rates of radicalization and ISIS-membership” are not grounded in solid data and it is not clear if radicalization is related to racial politics as much as, say, criminal justice issues. The absence of ethnic and religious statistics also makes it difficult to find a denominator for these countries. Further, the WVS is a very problematic survey of tolerance (Eurobarometer and the ESS are better at comparing European countries). I agree that the French allergy to ethnic statistiques is linked to their poor ability to effectively target marginalized groups, but I don’t see the causal relationship. I think your main argument holds even without this supposed counter-example.
