The point (one of a few) is that one can make and get away with making any and all sort of rules and guidelines, no matter how ridiculous they seem, as long as they don’t fucking moralize about it.
And if that sounds unappealing, that it omits the best part, one should really wonder and reconsider what the actual point of the rules are. A rule is just a fucking rule, to achieve a goal; it’s not a replacement and upgrade for an argument detailing why one’s position is morally and logically correct.
