Of course, that's how the right wingers take over the discourse of a topic. That's what happened to Pepe for example. It was a cute webcomic, that became a meme, that became a dogwhistle and now it's just a nazi symbol. You can't use pepe anymore without it being very clear that you're a nazi. But we're not gonna cede antizionism to the right wing. If people are serious about fighting antisemitism they need to make sure they know who their fighting, it includes zionists who fund and help out antisemitic causes to force jews to move to Israel so they can settle their frontier. And they need to make sure that they have their priorities in order, because right now islamophobia is a bigger threat than antisemitism.

The occupation regime of west palestine (and I'm using the whole phrase not just because it abbreviates to orowpa, which sounds like europa where the zionists actually come from, but also because "zionist occupation regime" is that well established a nazi dog whistle) is a greater more powerful threat than any antisemitic nazi group out there. So we're not gonna tone down our antizionism in order to avoid every antisemitic dog whistle out there, because

a) they're constantly evolving, it's impossible to keep track of every single one
b) by their nature need a wide berth, diluting the message. Being punchy, being direct carries weight and having to constantly talk about how you don't mean jews in general centers jews in a discussion about how a jewish supremacist ethnostate is trying to wipe out the palestinians. The palestinians need to be at the center here, not westerners. Jew or gentile.
c) the zionists will read every criticism of them as anti-semitic anyway

Antisemitism is becoming a cudgel, used to tone down and silence antizionism and you can thank the zionists for that. So be careful of who you're accusing of antisemitism lest it become completely meaningless and ask yourself why would someone try to covertly signal their antisemitism on lemmy? To what end?
