Why Do You Act/Talk White?

If you want to piss me off, ask me that question. Why do you talk/act white? I ALWAYS get this question. I always thought as I got older, people would quit asking me this dumb ass question. Seriously, I thought grown ass people would know better, but they don't. It really irks me. I don't talk "white". I talk like myself. Honestly, why is it that black people like to stereotype themselves sometimes, is it because they feel they have to? Why put yourself into the category of a stereotype. To me, that is nothing short of sad. We have a distinct culture, but that culture goes beyond how you talk, does it not? Or is the black american culture that shallow that we can't get beyond the stereotypical ebonics, hip hop/r&b culture?
