I agree that this sort of thing is bad, but that notion is starting to reach saturation level. At least for the things I read on the web. Boorish teammates, hostile speakers, misbehavior at conferences, people dismissing technical ideas for dumb non-technical reasons, etc. are indeed all bad things. Noted.

Also, maybe part of the problem is thinking/assuming that a bunch of front-end devs are going to be "your people". Yeeuch. It's a job, some of those people you will like and get along with, most of them less so.
