TBH I don’t care about antisemitism. So Twitter’s the way to go.
I think there’s a distinction between criticising the actions people who choose to act in accordance with religious Judaism take, and discriminating against anyone with Jewish ancestry, saying they control the banks, etc.
The first I would say is perfectly valid, as as with most religions, Judaism has bad qualities. But you have to be careful that you’re judging the choices and not the parts of a person that they can’t change, such as their ancestory.
Regardless of how you feel about Jews, Twitter is just not the place to be, for so many other reasons.
