Well as long as you don’t distance yourself from Zionism and all its implications that is the logical framework you’re operating in when you say "Israel has a right to exist“ or "Israel has a right to defend itself“, because Israel cannot exist without genocide and it defends itself against the victims of colonization.

Palestinians are people, which can be good or bad, same as Israelis. Israel as a state otoh is a settler colony that commits genocide. As easy as it is to say Nazi Germany bad or Apartheid South Africa or Soviet Russia bad, it is to say Israel bad, at least for me.

A state that can only exist through the subjugation, theft and murder of another people has no right to exist.
