This is a really good comment.

Basically, what you end up with are the exact kind of people who make up the bulk of the alt-right political movement. It's an ideology which is incredibly seductive to them because it seems to treat their concerns seriously, promises to address the perceived discrimination against them, and promises to put their oppressors back in their place while finally giving them the 'fair' shot at education and romance and employment that they deserve. You might also notice this rhetoric is basically identical to the one peddled by the social justice movement: the only real difference is whether or not you're declared to be privileged by the dominant culture.

On the radio the other week there was an interview with a demographer (Dan Cassino) that really stuck out to me as explaining the shift on 4chan from 'edgy' iconoclaism to somewhat harder ideoligical boundaries. He thought the central points of the alt right were that minority groups/women are getting special rights and special treatment at the expense of white males, and second that they're using fraud and corruption to achieve this, Transcribed quote follows

in the 2008 and 20012 data we have, you didn't see much of a unification of people with racial resentment, economic resentment and gender based resentment and by 2016 we're seeing all of those seem to be forming one dimension. That is, people who in the past were against gay rights weren't necessarily showing levels of racial resentment, by 2016 we're seeing those attitudes are starting to merge and we're getting one coherent political dimension that looks like the alt right.

in 2012 we asked in the american national election survey whether men were being discriminated against (which seems like an odd thing to ask in America that's why we didn't ask it before) [posters note; I don't agree with this and it seems like 'received wisdom'], and we found that somewhere around 20% of republicans said that men were being discriminated against in America. In 2016 that number more than doubled, we're up to about 45% of republican men say that men are facing discrimination in America. The idea is that white men, driven largely by economic resentment are being driven to accepting all of these views that were previously very very fringe views held mostly by white nationalists. The idea that jews and women and homosexuals are corrupting the political system and getting all of these extra benefits from it, that was not something we were seeing in mainstream ideology before.

But what's happened is that we have enormous levels of economic resentment, the way we haven't seen previously since we've been doing these studies since the 1960s, by economic resentment I mean people saying that the economic system is rigged against them, people like them cannot find a job, and that level of economic resentment that we saw coming out of the 2008 recession (remember that early on sociologists called it a 'mansession' and it was disproportionately white men loosing their jobs, that has lead to this racial gender and other resentments coming forward.

So people have been trying to sell this alt right ideology for 20, 30 or more years, pat Buchanan has been trying to sell it personally for 20 years and it never got any traction until very recently, and it turns out what was missing was that economic resentment where white blue collar men no longer feel like they can get ahead in society, increasingly they are blaming what they feel are special interest groups...[and that ties into all these other groups, we're seeing...] higher levels for instance of anti Semitism which is something we actually took off most of these surveys because no one was admitting to anti-Semitic attitudes any more, and we're now seeing people on surveys saying that 'jews tend to stick together', that 'jews are greedy'. People are willing to say things to an interviewer that simply weren't socially acceptable before.
