Obscenity isn't protected speech, nor is incitement, sedition, insurrection, demoralizing military members, etc. "Hate speech" may just be the last nail in the coffin full of boiling frogs.
What is actually controversial that is still considered protected speech?
As long as your "controversial' speech pushes the collectivist marxist/leninist/bolsheviks agenda then it's protected.
Criticism of the catholic religion is somewhat controversial, but it’s becoming more encouraged. However criticism of other religions is strictly prohibited.
Calling you a faggot seems to be protected.
It would only be protected if it weren't true. Fag.
Faggot!
Still protected!!
