If I had to turn to a religion, it would be Buddhism. It seems to be the only one that is concerned with how things are (or aren't), rather than how we wish they were.
Oh and I'm happy to see that the atheist bus campaign has started in Toronto. I'm less happy, though not surprised, that a lot of people have a problem with it. Up until now, there have been countless church signs and ads for various forms of Christianity plastered all over the place. They explicitly attack other beliefs systems and spread questionable beliefs. Yet this realistically cautious, positive little message is offensive?
Maybe they should fight fire with fire?
