No, most Israelis are from Arab states. About 55%-60%
But not from Palestine, that's the point.
No, it's not the point. Most Americans don't originate from America, but Europe. Should they go to Europe?
Most White Americans didn't immigrate into the country at a time when there was a large population that was already here.
The reality is, sad as it is, that diseaes the Europeans brought pretty much eliminated most of the Native Americans who might have bitched about Europeans taking their land.
Incidently, the treatment of Native Americans IS something Americans are ashamed of, and rightfully so.
The Zionists don't think they are doing anything wrong, that's kind of the problem.
