Those who can't tolerate the co-existence of the greatest and worst things protected by the principals which have expanded the internet across nearly two billion people comes with -- and would instead force those whose words and actions they dislike to sign off, should perhaps voluntarily sign themselves off. If you do not have the skills to negotiate a sometimes unfriendly world of words, perhaps you should curl up under a nice shall on the sofa and watch your network television. If you can not exist on an Internet of unlimited thought and concepts both foreign and highly offensive to yourself, then perhaps you do not belong here.  Preach! (BTW, "principals" are the headmasters of schools. "Principles" are the fundamental truths or propositions on which systems of belief or conduct are founded.)  Preach on.
