Zico, if I change the name of the god in question, you'll probably see what I mean.
Let's say everyone believed in Horus. Parents taught their kids to believe in Horus before they could think for themselves, leaders of the world prayed to Horus for political guidance, Horus believers held back science and discriminated against certain groups. Perhaps you'd want to say something then, at the very least to try and get humanity to stop believing in a mythical god.
Being an atheist says nothing about what I do believe.
I also used inverted commas around 'share', because very often religious parents indoctrinate children and act as if other faiths (or atheists) don't have a say. Like the Golden Compass idiocy - preaching, bullying and trying to boycott something they don't agree with, and trying to get others to go along with them. I limit my criticism to words on a computer screen. You won't have seen any atheists trying to boycott Chronicles of Narnia or Passion of the Christ. Our sharing of views came to commenting on the films, not mass email alerts and time devoted to us on the news channels. Let's just say they're a lot more forceful in their 'sharing'.
