I think it’s fine to point out that a majority of Jews are Zionists, but the implication that it’s ok to judge an entire religion by it’s worst members, even if they are a majority, is not ok. Because that’s how we people make the leap from “death to Zionists” to “death to Jews”. One is a statement of solidarity with the Palestinian cause. The other is just plain old antisemitism, disguised as social justice.
