I don't actually know where I could be sent back to. Has the Jewish Slav diaspora mostly returned to the old Polish-Lithuania area, or did most of that crowd end up heading to Israel?
Also how are we defining legal? My family changed our last name and lied about our ancestry because the U.S. was denying Jews at the time, but I think everything else was legal by the laws of the time. That's kinda why this argument doesn't hold up. The genocide of the natives was horrible, certainly, but a pretty large number of people didn't actually show up in the U.S. until much later. Are we still responsible for the crimes a country committed decades or even centuries before we started living there? because that opens up a much, much bigger can of worms globally.
Just call people out for being racist if they're being racist, which most of the types screaming about illegal immigration are. but there are people with legitimate concerns around legal immigration.
