The answer to your direct question is Yes, if is far less dangerous to our society to allow total free speech.
A 70 plus year experiment which included, among other things, a crackdown on speech by authorities, ended badly, with tens of millions being killed.
So you’re saying that people should have the right to promote bestiality, pedophilia and incest as well as homosexuality?
You’re sick. When the founders wrote the Bill of Rights, free speech was not meant to include promoting depravity and gross immorality.
And that is the way it should be - the way they intended.
