Earlier quoted context omitted.
Or the time they knowingly employed a Nazi
Are you arguing for a system where employers consider your political views before hiring you? And no this is not an attempt to in anyway belittle what Nazi German did during WWII. Assuming the employee you are referring to has never been engaged in such acts, though, that feels like a very slippery slope.
Yes? Such a system already exists and is currently in place in virtually every country in the world.
If I go online and trash talk anyone, that might prevent me from getting hired.
Similarly, if I work someplace, and I call my boss a jackass, I might get fired!
You're trying to invoke "political" as a sort of shield here. No, it's not just politics.
Its called being an asshole. Assholes might be unemployable because that's how human socialization works. Have you met a Nazi that isn't an asshole? Because I haven't. So, there you go.
