Yes, some people marching for Palestine are anti-semitic, support Hamas, and celebrate their atrocities. But they are a SUBSET of a larger group. Many supporters of Palestine hate Hamas. Many Palestinians are apolitical and are just trying to survive.

Yes, some Israelis (and non-Israeli Jews) use dehumanizing language against Palestinians, and are fine with (or even welcome) violence against Palestinian civilians. But they are a SUBSET of those who are mourning Hamas's victims, aching for thier loved ones in Israel, etc.
