Chickpea, I get it. And even after visiting and/or living in this area for 21 years, I still can't put my finger on what exactly is the difference, why I continually feel like such an outsider here. It's not necessarily just political or religious; I've loved and been loved by many people all around the country with radically different political and/or religious views than mine, including everyone in my immediate family.
I think those that have brought up traveling may be on to part of it, although many of the people that I know here are well-traveled. I've always quipped that everything that happens here is at least 10 years behind the rest of the country... which I always found to be frustrating. But recently I've come to understand that the people who love it here, who consider it paradise and are drawn to live here... that is one of the things they absolutely love about it.
There are some of us who are naturally progressive, always looking forward, wanting to be on top of the world and culture and new thought and all that is happening... and then there are others who like a slower pace, who aren't all that concerned with the zeitgeist and what's new, but prefer the comfort of the old and familiar, and focusing on their immediate surroundings rather than the broader picture. These two dichotomies can loosely be painted as liberal and conservative, but not necessarily in the political sense.
The internet definitely has changed things for those of us "liberals" who, for whatever reason, choose to stay here, even though that nagging feeling of alienation never really goes away. And that is not to say there aren't things about living here that I've grown to love; first and foremost the friends I've made... I have been lucky enough to befriend some of the most wonderful, talented, intelligent, caring, cultured, funny, and wise people that I've ever known while living here.
But I still have to constantly remind myself to focus on the positive, on the things that I do love about this place, rather than let myself get mired in the negative. It's definitely not easy, and I when I'm down I spend lots of time fantasizing about moving to places like Seattle and Boulder and Austin where I just know I'd fit in better. But then I get to thinking about all the goodbyes I'd have to say, and how I'd have to start all over again, and then I start to think that the old & familiar might not be so bad after all... ;-)
That's my long-winded way of saying "you're not alone."
