This isn't strange. Some on the Coli like to deny this shyt but I taught middle school and don't give a fukk to lie or pretend otherwise. A lot of little Blk boys are conditioned against Blk girls at an early age. Dominant beauty standards, negative stereotypes are a microcosm in school. This is why you will hear some Blk dudes say stuff like "I used to only like light skinned chicks growing up but when I got older..."
As for the young dude, He is autistic and thus even more susceptible to conditioning. He could be mimicking dominant cultural tropes. There is a good chance he doesn't even have that much interaction with Blk females. I used to teach kids lke that. He probably acted weird around one Blk chick who wasn't feeling him being social awkward and that is the lens he sees all Blk women thru. Because in the autistic mind that hates transition and change he is fixated on that.
The crazy part is he doesn't even have to have negative experiences with Blk girls to formulate these ideas. He can pick up on other Blk boys his age having disdain or in popular culture. Autistic kids can sometimes be uber-followers b/c drawing popular conclusions take less mental effort and align easier with their worldviews. They oftentimes get taken advantage of due to their inability to be flexible or understand social mental nuances.
I honestly think these kinds of discussions are important but she should have driven home the idea that in white culture, Blk stereotypes create conditions where blks are highly influenced to dislike their own. I don't mind the conversation as long as it is tied DIRECTLY to whites causing this shyt. Otherwise, it's attention whoring to me.
