Consider the fallacy, the 'paradox of tolerance'
The radicals would say that we must be intolerant of the intolerant and silence their political expression. And if we tolerate the radicals advocating that, their violence can spiral out of control and we wind up at a minimum with political violence like this, or historically its led to bloody revolutions and atrocities and mass killings. So we must be intolerant of those intolerant of intolerance. And back and forth it goes, making what seems like a paradox. At least, to morons. To people so deep into relativism their feet aren't on the ground.
In reality there are obvious rational bounds to civility we arrived at as a society because they make sense. Like the Overton Window. Speech and actions we tolerate because expression has inherent merit in fostering debate for our common good, speech we must allow but repudiate and counter with our own speech for its repugnant nature, and speech that poses immediate and direct harm without merit and can be criminal. The differences between them aren't indefinably subjective, we've spent centuries hammering out those distinctions in court cases and have the likes of Brandeis putting them to words.
Its really not hard for a well adjusted person to figure out whether speech has merit, whether its repugnant, whether its criminal. And defending the freedom of speech means more than just protecting speech from criminality, it means respecting people's speech with merit regardless of your opposition to it. Not seeking to punish them outside the law, threaten them, try to have them doxxed or fired from their job. And if they aren't making a constructive political argument, repugnant-but-protected speech can deserve public shaming and personal consequences. Because that's how we resolve the paradox of intolerance. We have to intolerant of those that violate the bounds of civility, whether they are motivated by their own false idea of the paradox or they're just dickheads.
