I think there's an xkcd alt text about that: https://www.explainxkcd.com/wiki/index.php/1357:_Free_Speech

"I can't remember where I heard this, but someone once said that defending a position by citing free speech is sort of the ultimate concession; you're saying that the most compelling thing you can say for your position is that it's not literally illegal to express."
