As too with hate speech, or rather, speech that is considered harmful to society. Blasphemy used to be amongst that list but we have since moved on from the state protecting the majority from religious affront to instead protecting vulnerable minorities from attack and dehumanisation. How hate speech in defined in law very much mirrors the definitions of harassment and assault (which you appear to have no issue with): it is not mere offence and intent is necessary.
> you have no such presumption
Don't I? Freeze peach purists tend to have very similar beliefs. Speak to one and you've effectively spoken to them all.
> Rhetoric doesn't kill people, people kill people
This seems rather incongruous with your earlier quote of how words can incite violence. It's also an extremely American phrase used there to dismiss calls for gun control. I have yet to see an instance where adding proverbial fuel to a flame successfully tames it.
> Have you considered allowing the speech and punishing those who act violently because of their supposed hurt feelings?
Who precisely are you talking about here? Don't hide behind implication, name them.
> as long as we can counter them by rational argument and keep them in check by public opinion
It's interesting that you would quote this because I very much agree: for as long as rational argument is able to counter intolerance, that's all we need, and anything further is not just unnecessary but detrimental. But when rational argument becomes ineffective, as we've seen, then rational argument cannot be solely relied upon. In an age of misinformation and disinformation, the notion of 'just add more speech, that'll solve everything' is not only exceptionally naive but demonstrably ignorant. One need only look at America to see what being the freeze peachiest country gets you. The UK and the rest of Europe have speech restrictions like hate-speech laws because we have intimate knowledge of the devastation of unrestrained hate. Hate cannot be reliably restrained by speech. You may find a case here and there, but it cannot stop a mob.

If I may make a comparison here, the murder of the CEO of United Healthcare has seemingly opened many people's eyes to society's tolerance of state-sanction death through delays, denials, and deposals, compared to society's extreme horror at a rich person getting gunned down. And yes, them being rich matters: I'm reminded of the sheer difference in effort there was between finding the doomed Titan submersible and finding the lost workers from the Francis Scott Key Bridge collision and collapse. Notice also Mangione's perp walk: you don't get that kind of display when the gunned-down victim is poor.
What I'm getting at here is that many people in society turn a blind eye to the death and misery caused by the system. He's not able to afford his medicine and died? He should've picked a better healthcare package or changed providers. The system is given infinite grace. But when [allegedly] Mangione shot that CEO, the notion that there may have been any justification for it is out of the question. He is infinitely wrong. It was odd watching news coverage of the shooting and how they tip-toed around trying to talk about this, compared to the typical US brazenness with every other topic.
This is circling back to your "punishing those who act violently because of their supposed hurt feelings?" comment. I have my suspicions on who you're referring to, and I'm probably right, but I very much feel like you're doing what I described above, here. It's giving "milkshakes are cement".
