I believe that a person has the full right to say anything they want, no matter how immoral or disgusting someone else finds it. Unless they're directly calling for violence against someone (no, hurting someones feelings and offending someone isn't violence, the Supreme Court has already ruled on that many times), or they turn violent, then that is the only time it should be stopped/investigated. Otherwise, it doesn't matter if someone says the most racist, anti-LGBT, Anti-Christian, immoral, crude thing there is, they have the full right to say it, just as anyone has the full right to respond to it.

And before anyone says, NO, I do not defend or endorse what the Neo-Nazi/KKK thugs said, nor do I endorse the equally-vile, Antifa (though they're far more pro-Fascism than they are against it) thugs.

The First Amendment protects the person's right to say what they want, it does not protect against any kind of backlash or any response from what they say. And, the same rule of violence applies to those responding, as long as it's peaceful and non-threatening, you can respond to your heart's content.

I don't really care where you fall on the political spectrum, the right to Free Speech is one of the crucial rights that makes America in particular, the most free country on Earth. Whether you're on the left or right, you should agree to keep and protect this right, as it's necessary to both sides. Limiting this right in any way is the most slippery slope into a totalitarian dictatorship.
