Obscene?

[frankthetank]

That´s why obscenity is used as a term to censor free speech.

You can´t define it.

Obscenity depends on taste. Taste differs from person to person.

So it´s a nice term to defend censorship without any checkable reasons. For example: I think green cars are tasteless. So they are obscene for me. So get rid of all green cars.
