I'd say you should stop being so resentful.

There are both shitty and amazing people in every social scene. In high school, I and most of my friends spent our day in the computer lab. We were nerds. Some of those guys were really funny, intelligent, kind people who just didn't have a firm grasp on how to interact with the majority of other students. But as they grew tired of being anti-social, not dating, and feeling like outcasts, they slowly tried talking to different groups of people and found others they could relate to as well. This happened to me somewhat, and by senior year of high school I had two groups of friends: my cool(er) friends and my computer lab friends.

The computer lab friends who chose not to go outside their comfort zone grew pretty resentful. In several cases, they didn't go outside their comfort zone because they were already resentful of people more "popular" or better looking than them. They basically psyched themselves out of a social life because they were intimidated. They stayed at home with their parents on weekends. They didn't talk to girls. They grew more resentful.

The ones who did found that some of their fears were well-founded...there are uninteresting, stupid, and mean people out there. There always will be. But there also a lot of genuinely nice people who are stumbling though and doing their best. Some of the "cool" kids have shit going on at home just like you: divorced parents, siblings with cancer, etc. And some are terrible people who you'll have no interest in being friends with.

(It should be noted that a few of my nerdy friends really had no interest in being social and just wanted to do their own thing. More power to them for figuring out what makes them happy.)

So many of my friends who are hipsters now are really just ex-nerd ex-super shy kids who've figured out how to be social. Is the clothing and hair sometimes ludicrous? Sure, but it's just a way to hide within a group, the same way preppy people or goths or cosplayers do. Are there poseurs and people who take it too far? Of course, but they, as in most groups, are often the most insecure and desperate to fit in.

As someone who still considers himself a nerd, but since high school has dated quite a bit and has plenty of friends, I can understand your resentment towards seemingly happy, social people who call themselves nerds or geeks. That's fine, but:

Resentment is just an ugly quality. It won't make you happier and won't make people want to be around you. It compounds and isolates you. So you can choose to be resentful of the stupid hipsters who don't meet your qualifications for being a real geek, or you can be the bigger person and try to figure out what common interests you might have between your "true" geekiness" and theirs.

Sorry for this long diatribe based on a meme, but I've just seen too many once decent friends get swallowed up in their resentment and turn into people who don't understand why they're lonely and are hard to be around, which makes them more resentful, and so on. Be happy with yourself and your own interests, and be actively interested in what other people are doing. You'll inform them. They'll inform you. And you should both be better off.
