I'm in Texas, but in a major city like Dallas, it's not THAT uncommon, though I certainly don't bring it up in interviews; in Nacogdoches (east/rural Texas), where I went to college, the Bible Belt was quite a bit more apparent, but when on campus, again it wasn't THAT uncommon, so I've never felt like I was in any real danger ... but then again I only told the right people, so there ya go.
Honestly, I'd say there's an age gap that determines how big a deal it is in most cases, as GamergirlBritt alluded to. I had mostly Christian friends and one of my best friends was a Bhuddist; I tried not to bring it up around anyone but my Buddhist friend, just cause we discussed philosophy all the time.
