The big mistake that most of the atheists here are making is claiming that every single belief system is to be equally trusted. They think that some "martyr with 12 followers" constitutes a religion that is on equal ground with religions such as Christianity, Judaism, Hinduism, and Islam.

A mistake made by Jamie is the point that all of the different branches of Christianity claim the others are wrong. This is simple ignorance. If 2 branches of Christianity agree on 95% and disagree on the 5%, that doesn't mean they both think the other is "wrong." The Roman Catholic and Eastern Orthodox churches, for example, have only a grocery list of disagreements - most of their differences have to do with church hierarchy.

Third, you'll notice that every religion does not say every other religion is "wrong." Christians and Jews, for example, share most of their beliefs in common!

Don't make it out that there's this massive war of belief among the faithful.
