You should read about the paradox of tolerance and why free speech should be limited to what doesn’t hurt or limit others’ access to freedom.
Being able to trash talk minorities (completely random example obviously) is not free speech, it’s hate speech that will ultimately devolve into atrocities.

Also, please share the kind of things that you think should be allowed without naming them (in full details like “racist slurs”, or “calls to violence against a minority”, or “cryptoscams”) , I think it could be interesting.
