People who say Palestine existed before Israel and Israel is a ‘new country that’s colonizing’ sound like flat earthers. Every piece of logic and evidence proves that is wrong, yet they deny, deny, deny and say that the government is lying.
I think we should approach flat earthers with "actually, a vastly more common and alarming misconception is not that the Earth is a sphere, but that the Sun is a sphere. That’s a lie. The Sun is actually a tube, and you’re only ever seeing one end of the tube"
