How do people in this day in age become nazis/neonazies sexist or even incels when there is so much knowledge against it? Do they get anything out of being that way?
There's a lot of information, there's also a lot of misinformation. Many people don't trust authorities, sometimes for understandable reasons, so they end up in the fringes.
Also, the Nazis, and even the Confederates, weren't all that long ago in the grand scheme. A couple generations. Many people learn these tendencies from their family.
Also incels are somewhat different from Nazis/fascists. There's obviously a lot of overlap. There's always been men who had trouble with women, but I think being a male virgin after a certain age is enormously more vilified these days than it was in, for instance, the 50s, even among more progressive, left leaning groups. Admittedly, that's anecdotal so I could be wrong.
Part of it is education and critical thinking. People don’t know what to trust because they don’t know how to test information for truthfulness and can’t reliably fact check. So they depend on an authority figure to tell them what and how to think, with expected results.
Note this isn’t limited to these people; some people just pick better authority figures than others.

Not sure if this is true, but I'm pretty sure that research says that people were having more sex back then. So probably fewer virgins back then.
There was less to do for entertainment in the 50s, lol
