Re: "only block those [..] who have never entered the country previously"
"people in the US forget that we are largely descended from immigrants"
Especially that guy who keeps coming up on the news? Can't remember his name. German ancestry - grandfather was German went to the US around the time of the gold rush. Father was born in the US but was such a great patriot he was accused of profiteering during WWII, and then also investigated for various Civil Rights Act issues (I guess being arrested during a Klan march will do that for a reputation). Weirdly although his father claimed to be Swedish, but the son has been talking nonsense about Sweden recently.
