Looks like a way to attack homeschooling.
I know the OP pretty well by now, his point is black people are judged so harshly, look at the white people, nobody holds them to the same standards we hold blacks to. It's a lame and stupid argument, but he makes it here everyday.
Hmm -- I see more a religious angle. That is, if we have to constantly correct these mythologies about "honor" killings and female genital mutilation as being "Islamic", then those same mythologizers should be in here claiming, by their same logic, that incest must be a Christian thing. Both are fallacies, but if you argue one, you gotta argue the other.
We hear a lot about incest from social workers in Carolina in the rural/dry county/hypertraditional areas.
Sadly this is not likely to be at all an isolated or unusual case.
