I read the post, very long, very confusing.
My first point about it, how was he 15 and in XGC?
My second, I've heard the term used in a derogatory way before and, to me anyways, the ban was just.
My third, I don't think it would be possible or acceptable if people like that came back into the community, I think racism is extremely horrible and a ban without a warning should've been expected.
My fourth, person who posted the thread will never be able to get the council to agree to a members that were "wrongly" banned back. Its a bad idea from the start. I don't care if the kid was a nice one, but since he is childish and a clear racist(in my eyes anyway) he shouldn't be allowed back in.
