I've been reading a lot of red pill stuff lately (while currently remaining agnostic), and my impression is that most of the prominent "red pill" writers are in fact really nasty. They seem to revel in how offensive their beliefs are to the general public and crank it up to eleven just to cause a reaction. Roissy is an obvious example. About one third of his posts don't even have any point, they're just him ranting about how much he hates fat women. Moldbug bafflingly decides to call black people "Negroes" (while offering some weird historical justification for doing so). Regardless of the actual truth of the red pill movement's literal beliefs, I think they bring most of their misanthropic, hateful reputation on themselves.

I haven't read Athol Kay, so I don't know what his deal is.
