no i wouldn't assume that because once again you are making the assumption that wearing baggy clothes is a black thing and IT IS NOT. when i see people wearing what they are wearing, i assume they are wearing those clothes because they like them or because they are comfortable, not because they are trying to imitate anyone. if Ruk is imitating anything, it is the hip-hop culture and fashion, not black people.
and sure it can go both ways but that doesn't mean both ways are right. if you see a young black guy from the ghetto working in an office and say "hey look at this guy, he overcame his environment and made something of himself" and i say, "fuck that nigger, who let him work in an office like he's white, he should be on the street selling crack," does that mean we're both right? of course not. i would be wrong for having those beliefs, the same way you're wrong in your beliefs that people who dress a certain way are trying to be something they aren't.
get it through your head that the clothes you wear are not an indication of who you are or what you're trying to be, but just the clothes you wear.
also, why is a suit and tie a universal thing but baggy clothes are not? who decided that suits are ok for every race but baggy clothes aren't ok for anyone other than black people? no one made that decision, that's just your own belief system that makes you think this.
