I was a JW for the first 57 years of my life and fervently believed in the Watchtower, the Bible and Jehovah.
I am now an atheist and am a better person for it. I am not hateful at all, but even a better person. Now I no longer absolve myself of responsibility...leaving "things in Jehovah's hands.". I actively take steps to help people now!
One way to help people is by alerting them to the fact that believing in an invisible sky daddy could be a foolish notion.
