Im a church going Christian and have no problems with Cding---I wouldnt go to Church dressed though, out of simple common sense, no more than coming to church naked.
There is really nothing wrong with CDing, as far as my knowledge of the Bible and theology goes. Of course, I'm a mainstream Methodist. you have troubles when you deal with "Fundie" (fundementalist) sects who base their dogma on "traditions" rather than actual scripture. If some old guy 300 years ago thought something was "sinful", then by golly, its sinful today, no matter how weak or "over interpreted" the scripture cited would have been.
Also you have what I call "screwball religions" who might beleive anything, but usally are based on a single line of scripture where where they are the only one doing it right and everybody else, who dosent belong to their sect, or even their church building is going to HELL. (Ya gotta kiss those rattlesnakes and have seven wives) And dont forget the "literalists" who fail to realize that the "Bible" is a translation---and might not mean exactly what it says in the english version.
To my experience those adults who dont believe in God were either raised with NO religion or had parents who belonged to a Fundie or screwball sect, that turned them off to it. They DONT KNOW what real Christianity is, so they are hardly in a position to judge. Everything they complain about--the intolerance, the dopey and dangerious beleifs, etc. are Fundie or screwball BS.
There is nothing wrong with good mainstream Churches. Most are tolerant, so long as you keep any 'disruptive" personal peculearities to your self. And the moral guidance is constructive and comforting.
