Why is such a powerful word. It's only three letters, yet the makes such an impact. Why can be used by a little child asking about a dying pet, or it can be used by a scientist pondering his latest discovery. The reason it's my favorite word is because the strong philosophical emphasis on it.
I have nothing against atheists, I just think that it is absurd that atheism would have a name. We don't have names for people who don't believe in the 9/11 conspiracy. We don't have names for people who don't believe in unicorns, or narwhals, or griffins, or dragons, etc. Why should we have a label for a person who doesn't believe in a religion?
