That's basically just saying that racism and hate speech are super ultra duper bad and we should outlaw things like that, as well as vastly expand what we consider beyond the pale so that it captures what are fairly mainstream opinions. I (as well as many others) disagree, and in fact I think that the people that argue for hate speech laws are far more dangerous than the tiny handful of actual white supremacists out there who are just losing their battle slowly over time.
Did you know that in the Aeropagetica, John Milton's 1644 pamphlet that is a landmark in the history of free speech, Milton literally said it was OK to censor Catholicism and superstition? [1]
Freedom of speech has always been subject to limitations, exceptions, and special pleadings. There is no absolute liberty, there is only freedom to the extent that society is indifferent to, or can at least tolerate.
"even opinions lose their immunity when the circumstances in which they are expressed are such as to constitute their expression a positive instigation to some mischievous act" [2]
[1] "Yet if all cannot be of one mind—as who looks they should be?—this doubtless is more wholesome, more prudent, and more Christian, that many be tolerated, rather than all compelled. I mean not tolerated popery, and open superstition, which, as it extirpates all religions and civil supremacies, so itself should be extirpate" https://www.gutenberg.org/files/608/608-h/608-h.htm
