Traditionally, keeping Discordian meant observing the dietary commandments of The Principia Discordia. Specifically no hotdog buns. Is this dietary rule still practised?
Did you miss the part where a Discordian is forbidden to believe everything he reads?
Also, there's another part of the book that says that they're mandatory*
*As part of a fully garnished hotdog every friday. Perferably this should be increased to multiple fully garnished hotdogs on fridays during lent. You should also eat as many hotdog buns as possible during passover, a bacon double cheeseburger on yom-kippur, and as much black pudding** as you can eat for lunch (preferably at high noon) every day during ramadan. These last four rules aren't in the book, but they're just common sense.
**The pig-blood based sausage, not the slime monster which splits into additional monsters when struck by a weapon that deals slashing or piercing damage.
