Birth defects follow. Altogether, 70% of Pakistani Britons are married to relatives.
The West is in a race between the dangerous social patterns that immigrants bring with them, and the assimilation to our social patterns. We are hampered by the fact that some of our social patterns are also dangerous. Pakistani Britons rightly fear that if their children do not marry safely within their own families, they may assimilate to the British pattern of illegitimacy, which is now becoming the norm among the native British population.
I am not for either wholesale assimilation or wholesale rejection of the host culture. And I am certainly not for restricting immigration just because the immigrants, if there are enough of them and have a strong enough culture, resist assimilation. I think each case of assimilation or not should be judged on its merits.
Mark Steyn, who publishes these scary facts, is worried that the relativism of elite culture in the West gives us no grounds to resist the bad practices that immigrants might bring. I think he is right about that. Things are worse in Europe and Canada than they are in the United States. But we also have a problem with spineless relativism. It is worth practicing vertebrate enhancement of our culture, in anticipation of similar problems.
