At some point we went from "this guy is saying some racist shit, let's tell him he's being a prick and perhaps explain why" all the way to "let's harass this guy, put his real name up, and start digging through his employment and make personal attacks".
At what point do you think that perhaps we no longer have any moral high ground and that the jerks on the forum may perhaps be us?
Are you genuinely surprised about this?
