from the heart-- Yes, they are. I've known Wiccans, for example, who are very happy and fulfilled. Conversely, some of the most unhappy and unfulfilled people I know believe in the Judeo-Christian-Islamic God. When I was Christian, I felt that I was living a very happy and meaningful life, and that has never changed. Do you honestly believe that Christians are the only happy, fulfilled people on Earth? Heck, even when I was Christian, I had to admit there were some pretty content atheists, Muslims, Hindus, Buddhists, etc....many of them even more fulfilled than I.
