What is it? I tried to look on their reddit, but I couldn't really make heads or tails of what they're talking about.
Basically it's a cesspool of extremely bitter and hateful misogyny. There's more to it, but that's really all you need to know.
that's not accurate. that characterization better fits r/GreatApes or the less intellectual areas of Stormfront, where all that goes on is a contest to cram the most hatred into a post as is possible.
RedPill isn't an echo chamber. it more resembles a secular religion/cult, with certain rituals (working out, sex with multiple women), semi-sacred texts/beliefs, repeated cliches, etc. despite all that it does deal with a significant social phenomenon -- the anomie of the young adult male -- which makes it interesting to study in a way that racial hate sites are not.
