No need to. It may not have been an outright claim that the bucket of antisemitism the progressives carry is filled to the exact same degree as the bucket of antisemitism the right wingers carry. But there was at least an implication that antisemitism on the left has increased since Gaza, and that it's obvious and everyone can see it. I just haven't really seen that, explicitly. All I have seen is criticism of Israel by the left that is conflated with antisemitism, or incidents happening in bastions of progressivism where the antisemitism is assumed to have been by progressives, based on location. I'm open to the idea that all this is true, since I have no dog in that particular match either way, I'm just looking for something more concrete than inferences.
