I don't think anyone here is disagreeing with your stance, so long as it applies purely to actions taken in the workplace. If someone brings that stuff to work with them, and spreads it around there to the objection of others, then yeah, a process should begin to either correct that or remove them (preferably the latter following the former; except in extreme cases, I am against immediate termination). But what the OP is talking about is someone who, as of now, has kept work and private life separate.
At what point do you draw the line? Would you fire someone if you found out their wife/girlfriend/whatever was a stripper? Or a prostitute? What if they ate meat and you were vegetarian or vegan? What if you were a Rangers fan and they a Celtics fan? You have to make judgements at work purely about what happens while at work (or as I said, things that concern work by association, like if he wore what was clearly a company uniform to one of his White Power rallies).
Well, I've been describing where I draw the line.
First of all, I think that people should be protected by the law from being fired "wrongfully", and part of that is that they shouldn't be fired for privately held political beliefs. This is in order to guarantee that we have
meaningful freedom of speech. What I mean by "meaningful" is that, since we spend half of our waking lives at work, and since we are dependent on our employers for our very livelihoods, then if employers were allowed to trample on our freedom of speech, then we would not have freedom of speech in a "meaningful" sense. Of course, this does not mean that we should be allowed to say anything we want at work: we still have meaningful free speech even if we're not allowed to read aloud from the Bible during our lunch breaks. However, it does mean that our privately held political beliefs, and our lives outside of work more generally, should be off-limits, in order to ensure that we have meaningful free speech.
However this argument only works where the speech in question is protected by free speech laws. What I am saying is that some speech -- hate speech -- is not protected by free speech laws. Thus, this kind of speech is
not off-limits; an employer can legitimately fire an employee on the basis of speech that is not protected by free speech laws. I believe that, for example, a manifesto commitment to ridding the country of black people is indeed a threat of violence against black people, and thus is not protected by free speech laws. An employer ought to be able to fire the employee if they sign up to such a manifesto commitment.

So can I fire Republicans for endorsing warmongering? Or proponents of capitalism in general for defending a system that is protected by force on the part of the government?
See how ridiculously subjective this is getting?
I'm really just trying to describe hate speech. I've tried to "ignore the law" and tell you what I personally think thus far, but at this stage, it's beyond my expertise. I'm sure hate speech laws are written a lot better than I am writing them now, at 11:37pm, with absolutely no legal training whatsoever.
And I'm sure that there are a whole bunch of people who think that hate speech laws are evil.
