So you're saying "revenge based" ethnic cleansings are acceptable? Because that's a pretty fucked position to take if you're being serious.

If you're saying it's acceptable to target Jews who have nothing to do with Israel over the things that Israel does or did, you're validating the argument about anti-zionism being rooted in antisemitism.

As to your point:

The original ethnic cleansings that occurred in Israel were two-fold.

The first was the Jordanians telling the Palestinians to get out and promising them they could return once the war had been won. The Palestinians left but the Jordanians (and the rest of the Arab forces) lost the war.

The second was the original conflict between the Arabs and Jews living in Mandatory Palestine.

When the British endorsed the establishment of a Jewish homeland in Mandatory Palestine and when the UN endorsed the partition plan to end the conflict, the Jews accepted and the Arabs rejected it.

You can't start a war, get pushed out by the conflict, then claim that you are the victim because you tried to kill off an entire ethnic group and lost.

That doesn't work.
