Oh yeah, on reflection I left a few things unsaid that I should've spelled out there, so just to clarify:
Regarding the uploader, it's probably worth saying that it wasn't uploaded by an open antisemite who straightforwardly endorses everything in the video, just by one of these attentionseeking clickbait youtuber wankers doing it in the format of "some protests happened in Bolton today, I was on the scene to cover what went on". Which I think changes things a bit - I mean, I don't think the guy is a good or an honest journalist, but I think that journalism should work as a defence at least a bit, people should be able to report on events where far-right weirdos are shouting horrible stuff without it automatically being censored and that's something different to some prick just saying all this to camera as their opinion.
On my reasons for thinking it's better to leave it up:
1) if anyone is thinking about making a complaint to the police, having video evidence proving that the antisemitic abuse took place is probably quite a useful resource to have
2) separately to any potential police complaint, if any independent researchers fancy having a go at trying to identify who this person is, said video is probably also a useful resource for them
3) if anyone is in an argument with any more "moderate" anti-drag-queeners - like
Cloo appears right now, for instance - who are trying to pass this off as just being about concerned parents worried about kids being exposed to sexual materials or misogynistic stereotypes in drag or whatever, then I also think it's useful for them to be able to show how extreme the actual protests are, and to ask whether people want to line up alongside the likes of this shouting nazi.
Admittedly, none of those reasons strictly require the video to still be online, as long as anyone wanting to use it for any of those purposes has a copy saved they can still use it, but since I don't/can't know who has and hasn't saved it, leaving it up for now seems to make sense to me (and also youtube might well ignore any report anyway, fwiw)?
Anyway, on that note, if anyone's curious about this Talmudic scholar, here's what he looks like:
