I'd say just be yourself, but being yourself is what's got you concerned about something as ridiculous as a beanie despite the fact that white boys also rock beanies. Sounds like you're just racist and don't want to be associated with "blackness."
Are you an idiot? I actually want to be black because I'd be able to wear whatever the hell I want to without being called an Asian who wants to be black. I want to be black because I see cool black guys hanging out in huge groups all the time. I want to be black because it seems like an Asian guy like me can never hang out with those groups of black guys.
I don't want the same thing that happened to Miley to happen to me. She started twerking, and everyone up in this started calling her out for "acting black." It's ignorant of those people as hell because what the hell is "acting black"? I just want to be me without people thinking I'm something I'm not. I love black people, hip hop, and hip-hop fashion.
You need to understand what I'm trying to say here.
