The problem is, people would probably not see themselves as stupid if they are not told they are if they are not close enough to god.
I know if I were god, I rather someone be honest with themselves and not believe in me then playing a slave to try to fool themselves in prayer and hope they they some day will. It's a waste of time and effort. I know after awhile parents learn to let their children be (In America) but if I were god, I'd had to do the same thing. No hard feelings on one person who loves me and the other who does not.
Honesty, humbleness, and respect are key here. In political-religion there is no such thing.
I cant count so many of the post statements like the one you post from many many posters Christians, Muslims, and even atheists! that devalue the choice of a person to choose how he wants to live his life, to who or what he wants to base his life on and/or serve, and to what he wants to learn more about what he does not.
