I think #kamala is right in some part as you are right in some part.

I think socialmedia which use algorythms to promote aggressive language, provocation with no other intention then to provoke someone, this does not add to free speech. It rather obligates people to read this in favor of decent more calm language.

But you are also right in the way, that hatespeech is defined from the reader and no objective measurement. And to defend democracy, we need to accept critique in all forms and allow bad language. It should rather be critiqued as well and be distrusted by the public instead of censoring it by police.
