An agenda "to take over the world", no.
What they most likely said is that it's an endorsement of Israeli appropriation of Palestinian culture.
That's what seems to be their position. You can make of it what you want. But there's no reason to spin what that they're saying into something exponentially and categorically different ("the Zionist agenda to take over the world"), with the clearly implied charge of antisemitism that goes along with it.
I'm not saying that's your intent -- but the phrasing is clear there, in your words. I suspect it's far more likely you just slung the phrase "Zionist agenda to take over the world" in there for the nifty emotive effect it seems to bring, without regard to whether it had any logical connection to what you were talking about.
Especially the pro Palestine crowd
Vaguely lashing out at some unspecified target here. Seriously, what is this supposed to mean? The hardcore social media addicts who grab the most attention -- mostly by pushing people's buttons, in this case obviously yours? Are they the "pro-Palestine crowd"? Is therefore everything they say representative of everyone who considers themselves "pro-Palestine" in some form?
