When you lose free speech, there won't be any debate about losing the rest of your rights. You won't hear about any rights violations. You won't be able to talk when your rights are violated.
How many FB memes have you seen that say “annoy a liberal, turn off CNN”, or something similar? Why attack free speech when you can use marketing to convince people to censor themselves, and encourage others to do so?
There’s already no debate. Don’t need the power of the state when you have consent being manufactured every day by bad faith actors.
Without free speech, you have no rights.
