I read something very interesting about this recently, I can't recall where, but I'll see if I can find it. It made some interesting comments about the first amendment. I suppose you could read it yourself and infer everything the article in question relates, but I've been too dumb to interpret the law. Every time I do, I get in trouble.
Also I found this quote, which I believe to be true:
Chris Bast says:
I've been banned from a number of forums. In most cases I was not treated fairly, I was cast out because my thoughts and ideals did not mesh with group. Other instances I clearly violated the rules. I don't sign up to forums with the intention of being banned, but it does happen, and not enough IMHO. I don't take a great offense to it in most cases. I've run into a number of cliques in real life that I didn't get on with, and they essentially banned me from their club, or never really let me in. It's perfectly natural. I don't necessarily like the cliquish, herd mentality, but I can understand why it exists. I've always been one to speak out against what is popular so I've not maintained many of these cliques either on the internet or in reality. Some people will accept you for having an unpopular opinion, but usually that depends on the opinion. I can't say I've always been as accepting as I should be to this type of thing.The First Amendment is only meant to restrict the government and protect public expression of speech. It has never applied to private forums. So no, it is not a violation of freedom of speech to apply rules to what someone is allowed to say in your private forum.
Think about it this way. If you host a dinner party at your home and one of the guests starts spewing profanity and creeping on every woman in sight, do you have the right to throw him out of your house? Of course. A private forum is no different. You are under no obligation to respect anyone's First Amendment rights in your own private forum. You can run that forum like the Stasi if you want. It's your house. You make the rules. If the guests don't like the way you run things, they are free to leave.
So in essence, and in a roundabout way from a private standpoint I think the Freedom FROM Expression generally dominates in private life i.e. you have the right ask someone to leave your personal property who may be saying things you don't like. The Freedom OF Expression seems to be more dominant in government interaction/protest or guaranteeing that someone cannot censor you in your private space. It by no means says anyone has to listen to you or put up with hateful or abusive language.
If you choose to extend those ideals into your private space, then good for you... but it's NOT the First Amendment.
Freedom of thought and freedom of expression also include one's right to not listen. Intentionally disruptive members in a community act to inhibit the free expression of thought by frightening or intimidating others from expressing their views.
Being a misfit makes you realize these things, and there really isn't much difference in reality to internet.
