Zionism is a fascist ideology based upon building an ethno nation states wherein those of other ethnicities are expelled or exterminated.
Why do other ethnic and religious groups exist in modern day Israel if they were all supposed to be expelled or exterminated?
Not arguing against the fact that Israel doesn't have equal rights for everyone. Arguing against the other person assertion that everyone was expelled or exterminated.
A right to territorial integrity and to not be attacked is literally the right to exist.
