I live in SW Washington state...a significantly 'liberal' area (though I've traveled and lived throughout much of the country). I associate mostly with academics, hippie types, and alternative lifestyle livers. They're usually pretty ok. However, there's still piles and piles of stupid all around us all the time. People wandering around testifying to any who will listen, people writing letters to the editor in the paper, people on tv/radio, people at school meetings, people running groups and organizations (like the scouts), people pushing their elected officials to be their kind of special stupid, etc.
I actually don't prejudge, but my experience has been that a LARGE number of deeply religious people are ignorant, abusive, hypocrites responsible for much of the worlds ills. Not all, of course. There are a few exceptions that relegate religion to a back-burner on simmer. Generally, however, I have found that atheists and spiritual people are ok to good (by my standards), and religious people are at best a coin flip as to rather or not they're going to suck utterly (again, by my own biased viewpoint).
