My DS (23) has pretty much stopped playing xbox live. his "avatar" on xbox is a black guy. while he was using this avatar he said he heard a lot of "fuck that, dump the N\***" and had a hard time being accepted into groups. He then changed his avatar to a white character and was accepted into groups based only on his competence.
There is no AIBU here tbh it's more the desire for white folks to examine their privelege.
