This is not a conspiracy theory. It's actual documented evidence. The Epstein files also shed light on this, Bannon traveling around Europe to fortify alt-right alliance and seed unrest.
Was he trying to seed unrest or was he sabotaging organic right wing movements that have less dumb shit in their program?
EDIT: Keep in mind that the right wing movements on which you have trained your impressions are almost always by definition the popular ones. Do people typically dig into niche groups that don't get traction for ideologies they already disagree with? Probably not, right?
The less dumb shit gave him a platform for his dumber shit. Which is why sane people try to stop the right wing shit at the less-dumb-shit level, before it gets out of hand. It's the clearly marked path to hell on earth. An inch in that direction is the WRONG WAY.
Everyone is pretty clearly paranoid about "the right wing shit" due to being inculcated with the story of WW2 in school.
Think about the political policies of Britain immediately prior to WW2. If a party today advocated just rolling back to those policies verbatim, they would be called Nazis immediately.
Just stop for a second before reacting - that's pretty weird, right? The policies of the heroes of the story who literally fought the Nazis, would today be put in the same bucket as the Nazis. Huh?
Same with American policies immediately prior to WW2. If a party wanted to roll back to that, literally Hitler! But that America fought Hitler. But that America would be lumped in with Hitler. Weird, right?
