So you tell us, what is a fascist? Reactionaries seem to alternate between displaying complete ignorance of history by thinking fascists are some subset of the so-called "extreme left" and indulging in the usual old McCarthyite red-baiting by denouncing civil disobedience activists as "antifa communists".
I'm also really interested in what you think are "crackpot conspiracy theories" from the left. I know of only one, "Trump is trying to subvert the election results in a conspiracy with some Republican Representatives and Senators." Totally crackpot, since you can hardly label something as a "conspiracy" when it is being done in the open.
