Moderation impinges on freedom of speech – I hear it from every swearing 12 year old and older. Yere. Actually. Freedom of speech and censorship are as neutral as gravity.
It’s what you do with them that causes consequences which can be judged good or bad by varied criteria. Isn’t tricky at all. Putting your critics in jail is unwise use of censorship. Yelling in my ear is unwise use of freedom of speech. Both examples have bad consequences, in different ways. And it’s best not to jump of tall buildings.
