Ever wonder how people get sucked into the Alt-Right culture? Here's a very good video describing how it often happens. To summarize, people get stuck in a self-perpetuating cycle. The further one gets sucked in, the more rhetoric they adopt and repeat, the more isolated they become. When they are rejected for their rhetoric, they see this as evidence of the Liberal snowflakism. The Alt-Right are fueled by anger, which is preferable to them, because anger makes them feel empowered.
It's kind of a long video, so there's a lot more to it than what I've said. But after seeing it, I think I understand the Alt-Right culture a lot better. They're a lot like a cult in the way they works, only the way they recruit is more natural. They don't go out and recruit people to their cause, but they wait for people come to them, and those people get sucked in and red pilled before they realize what's happened.
