That's a good question Apognophos.
I don't know how it is with the Catholics, but I don't find it to be the case with what I've experienced in visiting my Southern Baptist family's churches or with the Episcopalians.
That's not to say they don't have some beliefs that some may find off putting. But with my Baptist family members, I find they tend towards the belief that Jesus lives in the heart of believer. Therefore to not listen to your heart or be tender in your conscience is like not paying attention to Jesus. The believing individual is fully capable of being led by Christ. There's a bit more to it than that of course because the believer is expected to be discerning but there is a lot less interference in this matter than there is in a cult.
The Episcopalians are seen as somewhat soft on sin by the more fundamentalist groups, but they respect the fact that everyone has a unique journey with God and are careful not to overly tamper with that.
That's as far as my personal experience goes with religion outside the cult. But even so, I think it is safe to say that a wide variance can be found. Even to some extent within the groups I mention.
