Zionism is the use of the right to self determination of the Jewish people

Nope. It's explicitly a colonial project, always was.

their ancestral homeland

Your ancestors living somewhere a couple thousand years ago doesn't give you the right to kick out the people living there now. It sure as hell doesn't give you the right to commit genocide ti do so.

If you deny the Jewish people the right to self determination, but support it for others, then that’s antisemitic of course.

I deny the Jewish people the right to an apartheid ethnostate as I do with every other group with such aspirations.

It doesn't matter if you're Jewish, Muslim or Christian, Israeli, Saudi, or White American. Favoring one religion and/or ethnicity over all others is never acceptable in a modern country.

You can criticize Israel’s current actions in the war in Gaza

Thank you SO much for allowing me to do what every clear minded person with a conscience already does! So kind of you! 🙄

Many Israelis do that all the time and have since early in the war. Most of those protesting in Israel against the Netanyahu government and for an end to the war wave Israeli flags and identify as Zionists themselves.

Citation needed.

In practice, when people say they criticize Zionism, what they often actually want is for Israel to be destroyed

More tired Hasbara lies 🙄

If you're going to carry water for a fascist apartheid regime, could you at least be just a LITTLE original? Just try it on for size?

The state that is a home to and protects half of the Jews.

The state that breeds ACTUAL antisemitism more than any other entity in the world, making every Jewish less safe, by insisting on equating its atrocities with being Jewish.

The implications of that ends up pretty terribly for Jews

Yeah, you're right about that. Just in the opposite direction than you think.

If you want half the world‘s Jews to be ethnically cleansed

Another ridiculous Hasbara strawman. No part of anti-zionism calls for anything of the kind. It's pure projection from the defenders of the government ACTUALLY committing ethnic cleansing.

If anything, conflating Israel with all Jewish people is itself highly antisemitic, given that the vast majority of Jewish people in the world aren't committing genocide and genocide isn't inherently part of Jewdom.
