I'm merely making observations about the situation we have today. I think there is, indisputably, a rather distinct "nerd" culture. I think there's also a distinct "hipster" culture. Recently, we've seen more interaction between them within the software industry, and more interaction between both of those groups with society at large as software has become more widespread and integral to everyday life.
I'm not sure why you're apparently taking this so personally, or why you think my personal opinion of "hipsters" and "nerds" is relevant. This is all about looking at the big picture that currently exists, basically all of which me and my opinions have absolutely no influence or control over.
If you consistently have a problem interacting with certain people in the workplace, might I suggest looking inward for both the cause and the solution to that problem?
As a professional, I work with whomever I have to in order to complete the tasks at hand. But given how many of my fellow colleagues with all sorts of jobs and all sorts of background have similar problems with "hipsters", I'm quite sure the problem is not with me, and it is not with my colleagues, either.
Obnoxiousness and ego just happen to be two of the traits inherently associated with "hipsters". I can't help that, my colleagues can't help that, and even the "hipsters" themselves can't help that. It's just who they are; it's a big part of what makes them "hipsters".
If you wish to discuss this further, please return to the topic at hand.
As such, I think you're tilting at windmills here and have proven not to be above the kind of people PG is railing against. He uses the example of poor whites being racist against blacks. Are "hipsters" the only people you feel you can demonstrate superiority over? That's the only reason I can come up with for your post.
