Gorby, its a lovely idea. I agree with much of it.. But there are some aspects i dont.
I don't subscribe to the christain ethos completely anymore, although i do appreciate and respect some of the principles it teaches.
I also have seen that going back once you leave dosent convince anyone to leave, it only entrenchs them more. You came back, after all. They teach fear and propaganda regarding leaving and you or anyone else comming back only feeds the 'see we told you so ' aspect.
If your fading and stuck in then i do see great good that can be done but purposely going back just to try and set a good example is a journey into frustration amd self inflicted misery.
