There are many naive and misinformed posters in these comments, as well as many thoughtful ones. The basic truth is, you are entitled to free speech in the US, but you are not entitled to a platform from which to speak it. This is especially true if the platform is privately owned, as just about all platforms are. (I can't think of an exception offhand.) It doesn't matter in the slightest if some platform has monopolized the market. They are still not obliged to carry your speech. End of story.
