I would suggest that being in favour of open borders for some purposes whilst closing borders in completely different circumstances for completely different reasons should be permissible even in our very polarised political climate.

What does non-discrimination and political correctness have to do with the white Americans that were evacuated from Wuhan lmao? And the ones that returned from China in general? Or for that matter, American citizens in general?

Also, the U.S. has banned flights to/from certain countries during certain times.

I also find it interesting that inside of the US, states are engaging in NIMBYism to keep evacuees from being quarantined. Alabama's senator boasted of this yesterday, and I believe there was a lawsuit or something in California blocking some patients from being quarantined at a particular location.
