When talking about freedom of expression, there's always this subtle difference between "OMG I SWEAR, I REBEL LOL" and actually saying something significant. Rather than telling someone to shut up, you may want to tell them why exactly you think (emphasis on think; what you think is stupid may make perfect sense to other people) they're morons. I know, that takes 2 minutes longer than typing "shut up", but it tends to prevent topics from derailing into back and forth "shut up"s from all posters. It may surprise you to find that some people don't like having to search a topic for rare posts that make sense in a sea of swearing and personal attacks. Imho, it's perfectly possible to get a point accross without profanity or insulting people. It seems odd that most complaints about lack of freedom of expression often seem to come from the same people who don't deal with the opinion of others very well.

Or, shorter said: people pay for site, rest of us don't. People who pay own site and can make rules that they feel are right. I have always loved the JCF because it isn't drowning in profanity, swearing and personal attacks, unlike many other forums, and it would be nice to keep it that way.
