Wait people who are not US citizens/residents have a right to enter the US? Wow that's crazy. I knew y'all were liberal but I don't know you are that liberal. No other country I know of gives non citizens/residents a right to enter.

Who said anything about a “right to enter”? This is just about not massively invading visitors’ privacy for no good reason.

Of course, if you just don’t want anyone with intelligence or dignity to visit the country, this is great policy.
