That sounds like an actively hostile environment for anyone who is not already in-group.
Definitely, and I like the way you put it...because I'm sure it happens when less-liberal-minded people move somewhere more liberal as well!
Thanks, everyone, for your posts/responses. This has been very helpful.
I don't mean to minimize your experiences with this, as they do sound very frustrating, and although we are likely on different sides of many issues from your post, I totally understand the frustration with people aggressively pushing their views - whatever they might be - on you or mocking you for your views you have that are different from them.
I, too, live in a generally pretty conservative area, and although I grew up with many conservative views, I have changed in many areas as I've aged and not in others. That being said, even in the conservative area that I'm in, I've had some weirdly aggressively liberal perspectives people have thrust on me. In the past year, off the cuff, I've been heckled by someone for simply eating a Chick-Fil-A sandwich while minding my own business (ironically the other side of your post). I've been harassed for showing a video for work that happened to contain a picture of J.K. Rowling that I didn't even create with a demand that I somehow edit the video to take her off of it (for TERF views, not anti-Harry Potter is witchcraft nonsense). I've been mocked by an openly bisexual person for having my DS in dance class because that's weird for a boy to be in.
I can only empathize a little, because overall, I can at least relate to the majority of people here culturally even if I now disagree with them at least somewhat on their conservative views. I'm not a fish out of water so to speak. I have, though, tried to maintain good relationships with people who are aggressive with me on their views, as long as it isn't all the time, and they're decent folks. The first two situations - I still have a good relationship with both people. The third situation - that person is pretty much a jerk overall, so I don't really want anything to do with them regardless (and the situation of making fun of my son would have probably have been a huge damper on things regardless). That being said, I certainly wouldn't have anything to do with some of the people you mentioned - if they don't want to have anything to do with atheists, I mean, forget them of course, and if some people's beliefs are too far from yours that you can't tolerate them, that makes sense too. Other times, I try to ignore the agressiveness. I rarely challenge anyone on being aggressive unless we're really close, but I just try to overlook it if it's not the norm. Again, I know this is easier to do when these don't happen often.
All that to be said, I hope that you find good friends, that people don't harass you, and that hopefully some people who make an overly aggressive statement here or there turn out to be not as bad as they seem.
