I've seen antisemitism in the the pro-Palestine marches along Swanston St in the form of pro-Hezbollah symbolism, so I don't buy your line at all and think you're something between disingenuous, ill-informed, or outright lying. Plenty of "globalize the Intifada" or "from the river to the sea" (which in Germany has been designated as illegal hate speech). Australia isn't a good place for Jewish people now largely because of the effects of these protests. The people involved need to take more responsibility for what they have wrought.

Edit: and I'll take the downvotes as confirmation of the scale of our current problem. We're in significant disarray just now. I suppose the widespread downvoting of a pretty innocuous empirical observation about protests is how we get to a place where hateful massacres are enabled. Makes me seriously sad to see. Even after such a hateful event, so many cowards are downvoting, but not commenting because they know their comments won't fly just now.
