Can you see how the former is a link in the same "chain of destruction"[1] as the latter?

You may be disinclined to watch this short video, but perhaps you would be surprised to see that it actually gives strong credence to the problems which you are seemingly arguing against, and which I too care deeply about.

Getting someone fired causes them real harm. It's not at all out of the question that this harm could escalate to the point of imprisoning people or even killing them. The motive seems pretty similar to me. Don't forget that the ideologically motivated killings and imprisonments of the past were all justified using the same sort of arguments that you're making here, and the pattern of public denunciation is unmistakably similar. The arguments you've been making in this thread ("Speech that oppresses minorities deny their fundamental right to exist. Wouldn't you fight back if someone wanted to take away your life?") could justify action way beyond firing. If these arguments are valid, what wouldn't you have the right to do? If the harms being caused to date are "only" limited to firing, that's not because the denouncers are restraining themselves. It's because the protections of liberal society prevent them from doing worse. It's easy to imagine those protections getting diluted further, and easy to imagine worse harms than firing getting inflicted on people as a result. So I don't think this "what do they have to complain about" response is really valid.
