A good example of the free market providing rules is the Thom Hartmann forum. Thom sets the rules. If anyone breaks them, he or the moderator, can kick them off. It's his property. I don't have a right to post here. If I don't like this forum, I can create my own. Thom has the right to discriminate against anyone he wants. While we might object to arbritary discrimination, he has the right nonetheless.
