Isn't any musical trend likely to attract a bunch of posers? You can see it in grunge, in punk, emo, whatever. The fact of the matter is that some folks stay true to themselves and their look is very much a part of who they are because it reflects what's on the inside. The ones that are going along for the ride to "look cool" can be spotted by the ones who are the real deal.
Personally, I think Thatguy (for example) is totally the real deal. And I would venture to say that most people don't understand that some people ask themselves all the right questions to find their identity and to find the things that separate them from all the other clones. I'm not just talking about a physical look...I'm talking about what is beneath the surface as well. Sure, we can find others that share some traits or dress the way we do...but frankly, I'm most comfortable not conforming and doing my own thing. Or at least keeping things in perspective and laughing about what a joke it is to see punk rock posers or someone who takes something so literal that it becomes a blueprint for their life. I would guess most people can't get beyond the physical appearance of someone. Their opinion is already made and that's that.
