No. You are objectively wrong. It's great medicine that works -- for example, in Germany, and in the US, and elsewhere, it has stemmed the flow of violent extremism historically to stop the KKK and the Nazis. You can't even become a citizen if you have been a Nazi. Even on the small scale, like reddit, banning /r/fatpeoplehate was originally subject to much handwringing and weeping by the so-called free speech absolutists, but guess what -- it all went away, and the edgelords and bullies went back to 4chan to sulk, resulting in the bullshit not being normalized and made part of polite society.

If you want to live in a society where absolutely anything goes at all times, then could I recommend Somalia?
