That's untrue because there is always a remedy for speech, and that's more speech. Actual speech, in contrast to a boycott, or doxxing, or professional sabotage. "Make your argument", don't seek to prevent them from making theirs.
There's a difference between speech, and seeking to punish someone for their speech. Failure to recognize that spirals us to an ever-more authoritarian atmosphere until you find yourself the one being punished.
Boycotts are "more speech". Campaigns to refuse to associate with a person or company are "more speech".
The comment I initially replied to categorized "speech that demolishes the speech it is responding to". That's still speech. Trying to declare it off-limits, legally or socially, is still an attack on speech.
Similarly, your "punish someone for their speech" is... well, you're condemning people who responded to speech with more speech. Because you didn't like the speech they responded with. There is no way to be a free-speech absolutist and be against boycotts, blacklists, and all the other "authoritarian" stuff you're complaining about, because those things are just as much speech as what they're responding to.
The difference I'm trying to point out to you is that a free-speech absolutist gets trapped in self-contradiction. If they really are an absolutist about speech, then it doesn't matter if they choose to categorize some speech as designed to discourage or suppress other speech. They're still committed to defend it, and any action to stop or even just advocate against it would fall afoul of their own absolutist principle.
I do not start from a position of absolutism on speech, or tolerance, or a good many other things, and so I happily get to think through the nuances and have a much better chance of avoiding self-contradiction.
This is where Google dude's free-speech defenders get in trouble; many of them want to be, or want to be seen as, free-speech absolutists (if for no other reason than to say they don't agree with Google dude but feel obligated to defend his right to say what he wants). But they also want to condemn people who spoke out against him, called for him to face consequences, called for boycotts and refusals to associate, etc., and cannot do so without being self-contradictory since they themselves need to engage in "speech to discourage free speech" in order to do that.
There's a difference between speech, and seeking to punish someone for their speech. Failure to recognize that spirals us to an ever-more authoritarian atmosphere until you find yourself the one being punished.
