Free speech is important. Unfortunately, most people who begin threads like this have no idea what it means.
Free speech protects you from the government. It does not, has not, and will never protect you from social consequences. Not only are those social consequences somebody else's free speech, it's also their freedom of association. Nobody has to like you, nobody has to provide you a platform and nobody has to listen passively as you speak. That's not how any of this works.
Say damn near whatever you want. That's your right. Expect others to exercise their rights to say what they think of you and your speech in return.
