"Christian meat eaters" isn't a bad descriptional of America, actually.
I found this interesting because you assume most people are highly self-aware, take the time to weigh evidence, and are barely affected by the social world around them. Everything in psychology says you are wrong. Hell, you are a regular on a skeptic board. You really should know better.
For example, the the flavor and strength of religiousity is transmitted down parental and societal lines and conversion is uncommon. This is not a coincidence. People absorb ideas from those surroundings and never bother questioning them.
