Why lump Palestinians with what corrupt governments installed by the West (like Israel) hundreds if not thousands of kilometers away have done?
We already know how Palestinians treated Jewish migrations prior to Israel’s creation. When Europe was persecuring jews, Palestinians were teaching Jewish refugees how to farm (because in many parts of Europe, they weren’t allowed to).
But your “we have to massacre Palestinians, because what if we don’t, have you not considered they may massacre us too???!!”. This colonial mindset is nonsensical.
