I think your post makes a lot of good points, but I it really misses a huge facet of anti-fascist work that has been painfully neglected.

Probably the most unifying feature of alt-right ideologically is a belief in “race realism” or HBD. This is the result of a concerted effort to rebrand white supremacism/scientific racism as the “real science,” a truth that PC Jewish Liberal Academia is afraid to tell.

They frame their opponents as “race denialists” or “race creationist” to try to seize the narrative that they are the new Galileos.

iIt is increasingly sophisticated and convincing to a lot of young people, especially Youtube channels like Stefan Molyneux and blogs like the Alternative Hypothesis. They make these comprehensive cases that on the surface would appear airtight to a layman, but all you have to do is pull on any one thread and the whole case comes tumbling down.

But the problem is people aren’t trained to respond to them or know enough about the facts to debunk their case, so they usually just say “it’s pseudoscience” or “it’s racist.” And that’s the genius of the whole thing.

At that point, you have basically confirmed their whole narrative! “See?!? I was right all along, these science-denying Cultural Marxists are getting triggered by my hatefacts.”

They are an online movement and as much as we challenge them in real space, where the real work needs to be done is in virtual space. A lot of these guys are just young, dumb kinda anti-social kids who get a giddy thrill out of transgressive activities but then they get “red-pilled” by all this junk science, which leads them on that dark road to becoming more hardened white supremacists.

We need to strike at the pseudoscientific foundation of their ideology and the whole edifice will tumble.
