Yeup. One of my guilty pleasures is the"ask a manager" blog, and she (Jewish-American) had a Jewish-American reader write in the other day because someone had put up a swastika at her workplace and the company was failing to do anything about it. Just to prove that we need to be careful about antisemitic infiltration, this was an escalation from a previous piece of vandalism where someone had put up "kill all Zionists", which the company also refused to do anything about (and while that's fair given, y'know, Zionists, the fact that the follow up was a literal hate crime I think does paint a picture of what's going on there)
Of course the infuriating thing about this kind of antisemitic co-opting of antizionism is that it makes it impossible to reasonably say "well... Maybe Zionists ARE bad and it's no more unreasonable to say 'kill all zionists' than 'kill all fascists'", because yeah, when someone's putting up fucking swastikas you WILL look like a freak.
I dunno, fucking Nazis never fail to make literally everything worse.
