You posted proof, and for life of me i can't figure out why he would say that, if he is actually black. There are only two reasons for him to ever say he isn't black, (because only nonblack people lie about their ethnicities online. At most black people will exaggerate their mixture and try to claim they part cherokee or some shyt.)You literally admitted you aren't
Reason 1) Stating the obvious: He isn't black.
Reason 2) He's one of those foreign or mixed race type black folks who are on some me no black papi type shyt, and prefers to be called else like tyla. (but has since had a change of heart?)
