IMO those who don't like the moderation here should feel free to set up their own forum, where they can discuss what they like.
Every post here, and in every forum on the Net, is subject to an Admin or Moderator's whims and particular interpretation of the rules. True freedom of speech does and never has existed here, or in any useful forum: that's less to do with a curtailing of civil liberties, and more to do with proper [n]etiquette. You don't like it? Walk away. You'll save yourself a whole lot of bother.
