APC proves that you can get attention by looking great without having D&G monogrammed all over your jeans. GAP proves that you don't want attention, you've never in your life wanted attention in your life, and that along with liking bland jeans that only come from a history of blandness, you just might be a bland person yourself.
I don't know Brian. While I don't wear Gap jeans, and don't intend to, based on the same prejudiced you have, I don't think that liking GAP jeans in and of itself implies anything about a person's character. Context is everything. In fact, I would say that a real denimhead, (of which many of us are), who buys and wears GAP jeans irregardless that they are considered crap by his (or her, but most denimfreaks are guys) peers and who actually doesn't give a damn that it's not 5EPs, Corpus, APC, or whatever, is a guy with some real balls. This is analogous to the arguments I make repeatedly on the main forum to buck the rules, except that the rules here are less formal and made up by a bunch of people who would say that they hate rules, but live and judge by them nonetheless. In the same way that I would say that it's fine, even cool, to wear a tux (sorry, dinner jacket) with flapped pockets and single vents with a four-in-hand tie, as long as you can pull it off, and screw Flusser and his rules and his crappy haircut, you can wear GAP jeans with a Polo belt. There is only one condition - you've got to rock your own style, not be following whatever some book (Flusser, Roetzel, Manton) or the latest copy of Black Book tells you is *proper* or *cool*.
