Sounds like a false equivalency. People are fired for the things they say all the time, I'm not sure where lynching comes in.

Freedom of speech means the government cannot throw you in jail for the things you say. That is it. Short of violence, everyone else has the freedom of speech to tell you how reprehensible you are without limitations.

This idea that people have the right to say whatever they want without repercussions due to "freedom of speech" is a meme that needs to go away.
