Well once you bring law into it then you have to be accurate. Insulting someone is almost never unlawful in the US. And discrimination laws apply to specific matters for specific special classes.
You seem to be very confused. Even in countries like the UK with weaker freedom-of-speech laws, there are specific exceptions to slander law for insults.
Censorship is suppression.
Insulting someone or discriminating against them is not supression, it's unlawful.
If that's not your cup of tea, I'd challenge you to forego any and all (!) ameneties of modern civilized society to enjoy your anarcho-freedom.
Don't pretend to be a tough one by sitting in a comfy chair and picking the raisins out of the dough.
