You can see far-right parties surging across Europe. Speech restriction isn't just authoritarian, it's also counterproductive.
As an American I am actually quite worried about Europe's far right. Those guys are very scary, and it's creepy the way they have been able to influence the right here in the US. The MAGA movement was far more multicultural back in the 2010s, before Europe's far right was able to influence it with their ethnic cleansing and pogrom fantasies.
"Goebbels was in favor of free speech for views he liked. So was Stalin. If you’re really in favor of free speech, then you’re in favor of freedom of speech for precisely the views you despise. Otherwise, you’re not in favor of free speech."
