Oh look, a gish gallop tactic in the wild! Combined with some strawmen and moving the goalposts and the sealioning from earlier. You're just a lovely can of logical fallacies and bad faith debate tactics, aren't you?
All those words just to easily be disproven by the fact that the people who beat this shitstain asshole weren't members of the government in any way or form. They weren't even cops. It was other random citizens who beat him up. Ergo, not fascism when it's literally not the government doing it, aiding it, promoting it, or even siding with the ones who beat the asshole. In fact, the government arrested those people.
Oh, and just you get it out of the way - in the video, the ones beating him up aren't promoting their own ideology, they just think the asshole is an asshole for saying bullshit. No different than beating up a drunk at a bar who's calling everyone's mom a whore. So, not terrorism. Probably why they aren't being charged with terrorism. Not that you can trust the application of UK laws anyway as intended, but even a government happy to label every but of uproar as "terrorism" these days hasn't labeled it as such.
