Hm, it's interesting that there's 3 more, since I've only heard these. It's easy to see why they're left off, though, since, for many people, #14 contradicts #13, and somewhat #12, which, on it's own, sounds very conservative and narrow-minded when you get to the part about "expressing yourself," as if all the people who do so cannot actually be, in fact, expressing themselves. I mean, if a woman has her ears pierced, it's a childish bid for attention, not an expression of herself? Wow, don't even know what to make of that.
