They have less than NO idea what they claim and/or are lying. And sadly, almost nobody knows any factual history any more.
But I understand your analogy, at the end and agree.
Antifa ? No. I meant the old timers on the left, way, way back.
Close to 20 years ago, I was talking to some guy online who described himself as a (New York) Socialist. He had run for office as such. He was trying to break down for me (as someone on the right) the variations of the different leftist branches (i.e. Marxist/Leninist/Stalinist/Maoist/Trotskyite, et al). For me, it was just like someone getting into an argument over which brand of Mayonnaise was better. Aside from a different branding on the jar, it’s all basically the same. Just variations on anti-American totalitarianism.
Antifa is just your basic domestic terrorists of the ultra-left. Although I’m sure many Democrats sympathize with their agenda, they can’t openly support it (’cept maybe Maxine Waters) because it would cause them harm at the ballot box.
