Bit of a tangent, but I've got nothing against people's interests, however weird they may seem to me initially (fashion to me just isn't logical and I really, really don't get it.) But hey, if you're into that sort of thing that's fine by me, just don't expect me to join in or show any interest! Same as I wouldn't expect any random guy I meet to necessarily show an interest in programming or electronics.
What does annoy me though is when such people start telling me what I should be wearing and why this doesn't match and that looks crap and that's just been criminal since the 80's! And granted, it's not all of them but I've found far more people that do this with fashion than people into computers that say "wow, your PC is like 5 years old and not even overclocked and wow you haven't run windows update in a year?! You're sooo thick!" Wear what weird, wacky and wonderful stuff you like and I won't complain. Start trying to enforce that on me however and I will not be happy.
