Why do you feel this way – as in, why is this "asinine"? Anecdotally, I work with many people who frequently travel to the US, as well as a fair few academics over there. There is a clear general consensus that people are significantly altering their plans to reconsider travel to the US, and that others are actively looking to relocate. There is a very real—not imagined—possibility that some of those people will be subject to being rounded up and detained. The situation isn't obviously as severe as Nazi-era Germany, but it is absolutely true that people are being reminded of this. So why is the comparison anything other than apt?
