Principia scholars suggest that the ban from hot dog buns arises not out of scorn for dietary restrictions of other religions but true distaste for the state of hot dog consumption in society on the part of Mal2. An ongoing debate surrounds that line, one of the many contradictory and vague Discordian tenets. It is theorized that one side notes a lack of creativity in the time the work was written when it comes to hot dogs as a food, their dressing limited to classic mustard, relish, and ketchup. The hot dog bun is generally an enriched white flour good that adds little flavor or creative capability to the act of eating a hot dog. Mal2 was far ahead of his time in noting that a sturdier bun, such as that used to contain sub sandwiches, or even grinders or hoagies, allowed for greater addition of toppings for the classic hot dog.
Some go so far as to believe Mal2 was actually an adherent to the revolutionary hot dog movement of his time, a rather unknown collective made up of hot dog enthusiasts ranging from the most well known chefs to street corner vendors looking for the next step. Julia Child was also believed to be a part of this. If that's the case, it's actually amazing the impact that he had on the world of hot dogs. While the classic hot dog is still our cultural archetype for the food, many a specialty store are serving them on sturdier buns with toppings unfathomable in his day. I've even read of places which split the dog in half and then grill the inside, which is mind boggling even for my modern standards of hot dogs.
Still, a fervent debate rages over whether or not Mal2 was indeed making a commentary on the state of food in the nation, a timely remark well before such thinking became prevalent and necessary for our continued survival. Historically flour was eaten by peasants and common people in its whole grain form, healthier but less decadent than the white flour we see so often today. White flour was expensive and only affordable by nobility and royalty. With the advent of new techniques white flour became the standard in bread making, thus robbing many a people of the nutrition found in its whole wheat counterpart. "Enriching" white flour with vitamins to make it healthier has done little to mimic the benefits of naturally occurring wheat flour nutrients. Mal2, being the prescient mind he was, saw this as the conspiracy of depriving the masses of much vitamins for healthy minds on the part of those in power seeking to more easily manipulate them. Rather than complicate his statement with the proclamation to not eat any white flour based products or to consume only whole wheat, he decided in his wisdom to disavow only a part, to offer only a hint of what more lie beneath the surface - much like the Principia Discordia itself.
Yet others think it's total bullshit.
