Free speech does protect you to say whatever you want from government censorship. That's getting blurred here with most of the discussion circling around Twitter censorship.

I would still argue, though, that saying literally anything should be legal. Acting on hate speech, by plotting to commit a crime, may be illegal. The problem there is that you plotted a crime and in certain case that plot itself is illegal, it isn't about what you said but what you did.
