<------complete Agnostic here. not to shit on anyone's beliefs, but being brought up in a catholic household, i have come to the conclusion that organized religion is the cause to 80% of the world's problems, and the other 20% use it as an excuse to mask real intent, but since you asked, i believe in evidence, possiblility and human creativity. in other words, Science, Philosophy and Art.
I wouldnt deface my car with such things, but if i were to, i would get one of these bumper stickers.
I hope it doesnt offend anyone...i just find it funny.
