The "crying white supremacist" was a parking meter officer harasser (Colbert Report 2014)

Of course, nothing to object here!

My non-professional, internet-couch-driven diagnosis of some of these characters is based on having seen this before. There is more than the hate speech, there is a trance-like excitement.

Absolutely.

I didn’t mean that mental issues = racism; but those specific characters' excitement ~= mental issues.

There also another level, I guess more rooted on human nature. We are, in general, more prone to believe in false positives.

“The jews are taking your country” — that’s absurd. But wait, there’s a lot of people talking about, maybe that’s true? Better safe than sorry!

People in general have very low tolerance to ideas that conflict with their beliefs, preferring not being too analytical — we need simple models to interpret the world. You mix all this stuff and get bad results.

I think the challenge is to help possibly good people who might be caught into real asshole’s agendas.
