I disagree free speech also applies to institutions, social or cultural norms and platforms as Lemmy.

Lemmy is a protocol so there can be instances with free speech even if you don’t like it.

LibreWolf is better.

Censor and banning opinions and ideas you don’t like is anti free speech.

I disagree, free speech means the right to express any opinions and ideas without censorship or restraint even if you find them offensive.

You said you will remove any comment that is transphobic and ban if “you make an egregiously off colour comment”.

That is not free speech, and it’s ok. Your instance, your rules.

The good thing about Lemmy you can move to another instance with free speech.
