The term 'ginger' didn't become 'mainstream' just because of that South Park episode, I was being shot at, having acid thrown over me, stabbed, headbutted, punched, spat on, kicked, dehumanised, singled out, socially excluded, avoided, belittled, character assassinated etc since I can remember and to be fair I found that treatment was at its peak years before that South Park episode was even thought up.

Noticing my confusion here, I live in England and have never observed this level of prejudice. The kicking and punching I can just about believe, the acid is very implausible.
