Having grown up in that culture I can offer at least a little insight.
- Part of it is deeply ingrained gender roles. Eg what it is acceptable for a man to do. Bottoms in a gay couple are looked down on much much more than tops, because at least the top is doing the fucking and not getting fucked.
- Another part is definitely socioeconomic. In that level of poverty there isn't a lot that's in your control, but sex is. Giving up that control by "taking it" is considered bad.
The above combined with the culture of hyper masculinity propogated by gange culture and rap music just makes it very untenable. One of the worst insults you can say to someone from these areas would be to question their dad's sexuality.
You misspelled gang BTW.
I'm posting from my phone, forgive my one typo in my multi paragraph post.
Nah man, no worries. I agree autocorrect can be sometimes crap.
