I think maybe, too, that they get a bit discouraged on this forum. They may not be ready nor inclined to throw God out the window along with their religion, and JWD (imo) is extremely atheistic. Those that believe in a higher being and believe his spirit or essence is involved in man's physical and spiritual evolution have a tough time hanging on this forum.
I think it's necessary for us all to discuss and debate and comfort and support each other because of our common background. But, you have to have a bit of a tough skin to keep it up, because the atheists and agnostics can overwhelm some folks. Sometimes, they jump in and rip believers apart and if you're not confident or verbal enough to stand up for yourself and discuss and debate the issues, you can get scared off.
There are so many beliefs along the continuum from rabid atheists to syrupy holier-than-thou Bible thumpers, that you just have to be willing to examine them all, absorb, assimilate, or accommodate what you choose to but then learn to separate the person from the dogma. Don't let it color your caring and concern for the person.
