Not always, but yeah sometimes you're correct...
This is a Norteno rapper from a Sacramento gang called Broderick Boyz. If you saw dude anywhere you'd think he was straight up black, but his mom's is Mexican and he pushes Mexican hard. Obviously you can tell he black, and he pretty popular, there's black rappers who fukk with/collaborate with dude, but I don't know a black hood that functions with BB. As far as I know, he don't hang around or be with blacks, which illustrates my point, they not the majority but there are plenty of "blaxicans" who are like him and don't affiliate with black people:
For the record, I've never heard nothing bad on dude with blacks, just illustrating a point. Alota them Nortes though, they don't push NK like some Southerners do but plenty of em are racist as fukk and been into it with black hoods...
