We have so few black kids that there is no division. Black kids and white kids hang out all the time. Interracial dating is just a given. Besides, most of them have at least one white parent.
Having grown up in a city, it was quite a culture change for me.
My son tells me that most of the white guys he knows "boycott" girls who have been thus paired off.
Again, not really hostile in a cross-burning kind of way... just indifference and not wanting to be associated.
It's a poor joke, but I overheard one of his male friends quip, "Once she's gone black, she ain't going to be able to come back."
I think that once the novelty of interracial dating wore off, many of the young ladies couldn't get a date to prom or anywhere else. Word gets out.
