If you want to believe it or not, that's up to you. But if you're saying "y'all" that means there's more then just one. When there's smoke there's fire. But our experiences may just differ.
Now about the Carribean part, chilling in predominantly AA communities? Yeah you're correct. My parents live in Laurelton/ Cambria heights. It's a Overwhelmingly Carribean and African American community, so I had no problems with Carribeans at all ( Same homeowner associations, same schools, same watchdog group). But some of the Africans though

they we're just looking down on everybody.
Maybe you're correct, but my encounters with Africans make me believe otherwise.
