I'm not sure that isn't essentially the same thing, or can be.
Cultural pressures are powerful, and don't have to be overt. It's uncomfortable going against the beliefs of one's culture, and people do feel happy when they refrain from doing so.
One thing I've observed, and I'm not sure how relevant it is to this discussion, is that many "believers" are not really sure what it is they believe in. What I mean is that when asked to explain, or even state, a particular tenet of their belief system are unable to do so. The Bible says that? Really? The posters here are far from typical believers.
