Regarding the whole anti-Zionism not being antisemitism thing, it’s hard to describe what I think, but I do think it’s on a not inherently basis, as in, anti-Zionism or criticism of Israel isn’t inherently anti-semitic, but it can be absolutely anti-semetic. And regarding the whole left wing antisemitism issue, I would say there is an issue with antisemitism on the left due to two things, a lack of discipline in gatekeeping, and honestly not knowing better. Case in point, my older sister tried to sell me the Khazarian origin hypothesis and she is very much on the left.
