Firing a teacher because they are Muslim? No.

Firing a teacher because they were a member of ISIS? Yes.

Firing a professor because they a conservative? No.

Firing a professor because they are a Nazi? yes.

It really shouldn't be hard to make those distinctions in the majority of cases.

I think it would be safe to say that being fired for what most consider 'radicals' is the line that's drawn. Muslim is fine, but 
Al-Qaeda is not, etc.

[quote]Im really not sure how this would play out with an actual federal employee. What would be the legal standing of a State Department employee if they showed up at a pro Nazi rally?

I got curious and I asked my law-school friend who I game with on the weekends, and he said there is a very broad discretion with firing a State Department employee because they are technically not a protected class. But they'd still need to be provided with all of the severance benefits of a regular downsizing, and you'd need to be careful not to demean or slander them or they might have ground to sue the most benign thing you accuse them of. If you call them a Nazi slut, they can sue for the slut part if it was apart of the firing accusation, lol.
