You're probably right, they seem to care more about Israel and not Jews (or Palestinians), and especially care about "Israel as a concept" and to use it as a means to an end.

You're correct that Christian Zionists only care about Jews to the extent that the right number of them will be in Israel to be killed as part of the End Times prophecies based off of Revelations. But they are fanatical supporters of the state of Israel because they see it as necessary to bring about the rapture.

Top donor in the last 3 elections (combined) to Trump is Adelson Clinic/Miriam Adelson. She didn't spend all that money for nothing.

This is one part of a large pattern of Republicans trying to end-run around the First Ammendment specifically to defend Israel from criticism. For instance, in Texas they make school teachers sign contracts that include terms forbidding criticism of Israel. Republicans have also been extremely reliable supporters of unconstitutional Anti-BDS laws.

Make no mistake, the Republican party (and half the Democratic Party FWIW) is fully captured by the Israel lobby.

The ability to criticise authority is a defining right of America. How are these teachers supposed to teach the First Amendment?

> if you replace "Zionist" with "Jew"

I've never understood this kind of argument. If I replace "Zionist" with "elf", then the anti-Zionist movement would be anti-elf! Oh no!

Except that no one is replacing anything. The anti-Zionist movement is exactly that: anti-Zionist.

Antisemitism is real and a problem, but it's not the same thing.

> if you replace "Zionist" with "Jew" you're at Goebbels levels of antisemitism

This is a weird statement. It seems to suggest this as a reason not to criticize Zionists but if you replace "fascist" with "Jew" you're in a similar situation and that doesn't mean people shouldn't criticize fascists.
