I find it pretty hard to believe that if Clinton had won, this wouldn’t be happening, which is the logical conclusion of that position.
I suppose reasonable people can differ, I’m not claiming it doesn’t exist but I find the atmospheric effect claims in general overapplied. Not every racist, sexist thing in the world is due to Trump, as there was plenty before and would have been plenty under a different president. The number one worry in any firing is a lawsuit; their calculus surely would be centered around that, and any judges that would hear this case were in place long before Trump.
