You're right. I did misrepresent the situation. I've had quite a few positive experiences there too. Some of the best feedback I've gotten from this thread is that I should be looking at my own behavior and considering whether or not I'm doing my part to learn and be friendly to work with. I still may consider a job change in time, but I should be careful about where I place blame and what accusations I throw around.
There's not even one example where they reacted in a "nice way"?
Seems you haven't told them how such thing make you feel?
Maybe it's not personality, and perhaps they don't know this stuff is bothering you...
Definitely talk to your manager, and try talking to your team as well.
Focus on observations/examples as well as how those situations make you feel.
I agree that life is too short, and IT is full of "difficult" people. Instead of running away from it, get better in dealing with them.
