You DO understand how it is you are able to even HAVE an privately-owned forum, yes? It is allowed by the very piece of paper I mention previously, the very same paper that allows freedom of speech. I merely point out the hypocrisy of people like you who believe you give people the right to freedom of speech, when it is an national right. Hiding behind the 'privately-owned' claptrap is for the Lefties. You are a Lefty Loon? Alrighty then.
You have no idea what you are talking about. As proof, I can ban you right now (should I want to, which I won't) and deny your ability to say anything on this forum. That would NOT be a breach of the United States Constitution or a breach of law. It would be COMPLETELY legal.
