Quit it with the fear mongering
As a Canadian, I'm refusing to travel to the US right now, despite working remotely for a US-based company.
It's not fear mongering, it's real. But my motivation isn't even just fear; staying home or choosing to travel elsewhere (Europe, Asia, Mexico) is standing with my countrymen against a regime that doesn't respect our sovereignty or even its own laws.
Also the media doesn’t always report the full story. Often the people arrested have some small/medium offense from years ago.
Unlikely to happen to legal immigrants.
