But (again, "I think" and this doesn't necessarily express the views of anyone else) more to the point of this thread...
I am not Catholic, never have been, never will be. I respect those who are, and support them in their Christian walk. I have some notions about Catholic doctrine being in error. I will NOT go in the Catholic forum and post on every thread about how wrong they are, based on my preconcieved notions. I may pop in every now and then to ask about what they REALLY believe, or even just to read quietly to see what is being said. I may learn something, I may just get mad. And at the end of the day I might talk it over with my DH. But I won't debate with them or try to convert them. I won't even start a thread in general theology titled "Why Catholicism is wrong," though that would be allowed in CF; I just don't think it would accomplish anything. If someone started a thread asking why Protestants don' do XYZ that Catholics do (or whatever) then I would feel free to answer as politely as possible.
Do you see the parallel here? There's just a HUGE difference between going into someone's fellowship area and blasting it all to pieces, and opening dialog in a nuetral place.
