No, they defederated from feddit.org because it is a Zionist bar and its moderator teams conflate Zionism with Judaism just like yourself is doing here. Someone who says Palestinians were not ethnically cleansed during the Nakba is a Zionist, and his propaganda never gets removed by lemmy.world. I was accused of being a tankie while I oppose Russian imperialism; it doesn't mean tankies do not exist on lemmy.
A call for killing Zionists who are not involved in killing Palestinians is disgusting. It is also disgusting to say it means killing Jews when there are many anti-Zionist Jews and a lot more Christian Zionists. The closest thing to Nazism is Zionism.
