Be alert for THEM, be THEY big or be THEY small. THEY are anyone who tells you that they know best, anyone who wants you to do what THEY tell you. Including Mum, Your School, The Government, ALL religions (including discordianism), the government and greenpeace (eco-socoieties and the like have as strong an opinion on how you should behave as any of THEM) - Fanatics are part of THEM, too y'know.
Here's what the Principia Discordia has to say about them:
The seeds of the ORDERS OF DISCORDIA were planted by Greyface into his early disciples. They form the skeleton of the Aneristic Movement, which over emphasizes the Principle of Order and is antagonistic to the necessary compliment, the Principle of Disorder. The Orders are composed of persons all hung up on authority, security and control; i.e., they are blinded by the Aneristic Illusion. They do not know that they belong to Orders of Discordia. But we know.
A person belonging to one or more Order is just as likely to carry a flag of the counter-establishment as the flag of the establishment-- just as long as it is a flag.
Don't let THEM immanentize the Eschaton.
Go To Your Left-Right....
-- quoted without a hint of a sniff of a scrap of permission from the Principia Discordia
A cautionary note - don't reject out of hand everything THEY tell you to do. For example the goverernment says DRIVE ON THE LEFT and DON'T KILL PEOPLE. If I had a car I would drive on the left, not because I have to, but because that's the sensible thing to do (If you don't want to be a bit dead). I don't kill people partly because I don't want to get caught and partly because I don't want to live with the guilt, but mostly because I'm just to lazy.
Of course THEY tell you not to take drugs - now you'll have to decide that kinda one for yourself, won't you?
