Freedom of speech.

Freedom of Speech means you have the right to say anything that you want, but it does not mean that you will not be held accountable for the things you say. Be a grown-up. Take ownership for what you put out into the universe, especially the internet universe. If you act as a person of integrity would, then you will have nothing to fear. If you are a horrible human being saying racist, sexist, classist, homophobic vile, expect to get backlash and for there to be real world repercussions to your actions.
