How do I get my black stepbrother to get more in touch with his roots?

My parents (we're white) adopted him when he was young. I love him but hes 14 now and I feel like he should get more in touch with his roots. He listens to a lot of white music. I dont know why.

Like he literally listens to EDM. I dont understand it. Im white and i dont even listen to that. I can always hear edm coming out of his room and it confuses me.

I've tried to get him into guys like NBA youngboy. Like I gently nudge him into that. I play it out of my phone when we're all in the living room and ask him if he likes it.

He usually just says its alright then goes back to what hes doing. It kind of annoys me. I just feel like hes shunning a part of himself.

He gets good grades and everything and wants to be a pharmacist but I just feel like he should be doing more black things, you know?

He doesn't even like basketball or anything. I turn it on sometimes and he just tunes it out. I try to get him into it. But hes not interested. All he cares about is white music and anime.

Next thing I know he'll bring home a white girl.

What do I do? I feel like hes headed down a really bad self hating path.

wtf goin on in this thread
