I would not work with anyone who held those views, regardless of which country they were from. I find it abhorrent and especially so in the context of work.
But how do we all decide for ourselves what is abhorrent?
Hopefully by some sort of reasoning right? (And hopefully not as tortured and ill-advised as what RMS wrote all those years ago.)
The same reasoning that says it's bad to murder someone. I would say empathy and a modicum of human decency.
