Free speech requires tolerating speech you don't like. But it's worth it. Otherwise you get what the Left is doing, which is censorship and that's about as anti-American as it can get.
Free speech means you can say anything you want without the government interfering. If the speech threatens someone with violence, then that's where it ends. Calling someone the n-word isn't a violent act, it's just calling someone a name.
WHEN THE LEFT SAYS THEY'RE FOR FREE SPEECH, THEY'RE TALKING ABOUT SPEECH THEY AGREE WITH; WHEN THE RIGHT SAYS THEY'RE FOR FREE SPEECH, THEY'RE TALKING ABOUT SPEECH THEY DISAGREE WITH
