Amazing the backlash from seemingly-intelligent individuals against OP complaining about a very real problem.
The whole idea that "non-conformists are more annoying, are hypocrites, etc." is a non-starter, for the most part. I mean... sure, there are transparently fake non-conformists like hipsters who really are disingenuous and annoying, but that's not really what the OP is talking about.
Take a look around you, for once. Tons and tons of people -- the vast majority, in my experience -- really do take conformity to an unreasonable extreme. They very consciously compromise their inherent preferences, personality traits, etc. if they happen to be unique. It baffles me that so many of you can act like this is a good thing, or even neutral.
Here's some food for thought, next time you want to scoff cynically at someone who dares swim against the flow: the vast majority of truly impactful figures throughout history were real nonconformists who would be laughed out of most high school and college campuses today (and perhaps were in their time, too). Lapping up our commercialized, reality TV, low-IQ-catering mainstream culture may be a guaranteed ticket to acceptance, but it's also a guaranteed ticket to mediocrity and irrelevance.
