There are many Jewish people who criticise Israel’s human rights abuses in Gaza City and the West Bank. It is not antisemitic to criticise Israeli government decisions.
There are many Jewish people who criticise Judaism as a religion and a collection of ideas. In fact, because they’re the ones who know the most about it, it tends to come from Jews more than anyone else. It is not antisemitic to criticise Judaism as a religion.
If the only response you have to any criticism of Israeli government decisions or Judaism is “antisemitism”, or if you think goyim are not allowed to have opinions about the political situation in the occupied territories, you are doing the Jews of the world, and their diverse opinions and identities, a horrible disservice.
Yes, I know who these guys are and why they are protesting.
