I’m not quite sure that belief in zionism is measurable, but I’m sure you can find a source about antisemitism and zionist actions by Israel.

Anecdotally, I haven’t seen as many “stop the hate” campaigns that are basically about antisemitism as I have since the major military actions started in the Gaza in my lifetime.

I’d look it up if I really cared anything about the outcome of the discussion but it really doesn’t interest me that much to be honest.
