I have to say that most of the elders I encountered were liberal to moderate. Sure, there might have been the occasional uptight a**hole, but that was definitely the exception. Of course, this was my experience in various congregations in the SF Bay Area. I've heard that California congregations tend to be more liberal. I can't imagine some of the crazy conservative policies I've heard through the grapevine would ever fly here. Publishers would either just ignore them, or move to one of the numerous neighboring congregations where they would be welcomed with open arms.
My overall impression was that these were just normal guys doing their day job, then struggling to get through all of their elder duties on top of that. I hardly ever got a pretentious attitude from them, but I was always fairly friendly and social around them, and never caused any waves, so they probably liked that. I've had more then one on occasion admit to me that they disliked being an elder, but felt a responsibility "to help the friends". Most of them loved to drink as well!
