Yeah, those are hillbillies - they are all over the place. Many of them are actually homosexual believe it or not. If we are talking bumper stickers though, can't say I've come across many anti-LGBT ones. Mostly confederate flags and black and white flags with blue stripes all in the generic grab bag of generalized hatred. I stay away from those people / areas as it's just not my crowd, but not sure what this has to do with the safety of LGBT visitors to the US. Linking these stickers to that is a pretty broad sweep.
