I disagree. Antifa is an extreme manifestation of a general ideological trend that has its roots in post-modernist thought which has come to dominate the humanities and, to a lesser extent, social science departments.
Post-modernism has its roots in the works of men like Heiddegar (who ironically was a Nazi), Derrida, and Foucault (who ironically died flirting with Stoicism). You can think of post-modernism as essentially the position that truth doesn't exist, reason doesn't exist, and claims to knowledge are merely discourses between inherently opposing and adversarial power structures. A lot of it is self defeating, but because they have dispensed with the logos they don't seem to mind, and have essentially been producing masturbatory drivel for the past half-century, especially since most of the people who engage in it now do not have the raw intellectual quality of some of the founders. And that's no surprise, because the only sorts people going into this stuff anymore are followers and sheep - the sort who never question what they are taught by their professors, who themselves were a bunch of followers from a previous generation. In any event, this in combination with the various subgenres of cultural studies, have essentially established a cult that students are indoctrinated into.
