As somebody living outside the US, I would find moving to the states highly undesirable even if it wasn't for the hostility towards non-US citizens. To me, it would mean a significant reduction in quality of live and I am low-key scared of all the ingredients and additives in food that are pretty much banned everywhere else. Not to mention all risks regarding healthcare.
I live in the US. I disagree about the hostility towards non-citizens. If you are talking about ICE, it's more about racism. They are not gunning down Brits, Germans or Australians. Agree about the rest. Can I come live in your country? :)
I don't know their heritage, but both Renee and Alex were very white (not that it should matter) US citizens, savagely murdered by ICE.
So yes, ICE is gunning down pretty much everyone they see.
