all the smart young people are racist, sorry to break it to you.
No, they aren't. But that depends on your definition of racism. Hating another human being for his appearance is a shallow, stupid reason. Hating anybody is a sign of lack of mental maturity as it hurts you more than anyone. All racists in this sense are idiots. If you're talking about "natural" racism where we make quick judgements about people based on their appearance, including race; "oh he's black, he's probably poor", "oh she's Asian she's probably smart", then this kind of thinking is pretty normal and how our brains evolved to quickly access another human. Still obviously inaccurate but seems to get the job done.
Anyway, I'm ignoring all the nazis of the codex and there is plenty of discourse left that is free from racial slurs and such. Racism is whiny bitch behavior, I thought it was funny at first so I played along until I realized many of the people here truly feel that way. Sad and pathetic people.
Because the codex allows all kinds of shizos, these people flee here as their last bastion. That doesn't mean that they are smart, or among the top quality posters (they aren't).
A lot of them are bottom-tier shoutbox dwellers.
