I'm going to rant a little bit for a second and surely offend some of you.

I am really getting sick of people who try to argue that they have unlimied rights to speak on private websites. 

Freedom of speech doesn't exist in the private sector.  The first amendment applies to what the American government can do in terms of passing laws against freedom of expression.

The private sector, such as websites like these, can restrict speech in any way they want.  That may seem harsh and unfair but ultimately the private sector is governed by the open market.  A website that is excessively restrictive will find itself lost in the dust as users go to other places to express themselves.

However, sites that are too free with letting people speak will end up a nasty mess of anarchy as the lowest common denominator of users end up taking over.

And in between there is admin discretion.  For instance, I am sometimes amazed at how much effort some users will go to antagonize an admin.  As if admins are "the police" and there's some sort of federal rules to govern them.  Admins can zap users on the sites they admin for any reason they choose. Yet some people don't recognize that.  They keep pushing and pushing until they get kicked off and then start screaming censorship.
