The Right to Free Speech means the government can't arrest you for what you say.
It doesn't mean that anyone else has to listen to your bullshit, or host you while you share it.
The Right to Free Speech doesn't shield you from criticism or consequences.
If you're yelled at, boycotted, fired, banned from an Internet community, beaten up or even get shot by a gun, your free speech rights aren't being violated.
It's just that the people listening think you're an asshole.
And they're showing you the door.
