Well, see, here’s the thing.  White people (broadly) have been largely not-marrying-their-cousins for a while now, and they live in societies in which cousin marriage is fairly taboo.  So when white people marry their cousin, it typically is a one generation thing, preventing a whole bunch of snowballing consequences.

I’m sure it seems otherwise on this blog, but I actually don’t have a strong disgust reaction towards cousin marriage.  And if we continued to see rates around 1%, I wouldn’t really care.

But some populations have cousin-married at much higher rates, for much longer times.  So one generation of cousin marriage for them isn’t the same as one generation of cousin marriage for other people.

It isn’t “too late.”  Humans are resilient.  We just have to have them stop doing it now.

Since we don’t have the full lineages of everyone, and I don’t want to go by other categories, I’d rather just throw the (very tiny) baby out with the bathwater and ban it for everyone.

Also, a big chunk of the tight family control aspect is cultural transmission.  So now I’ll have to actually make that post about cultural transmission (generally) at some point, seeing as some things like FGM are cultural so cultural transmission isn’t all nice things like ethnic foods.
