anyone that claims to have any god worship needs to do one thing:
provide a single piece of proof that follows evidentiary procedure that their deity is real and not a figment of some sick and twisted bastards imagination
Or a product of wishful thinking.
I was raised catholic myself, but I called bullshit on that when I was about 10, a lot it was just too anti-logic and pro-authority for me to swallow. Went agnostic for a while, then spent most of high school calling myself a wiccan (a moral system that boils down to 'don't mess with people' was very appealing to me), but now I'm just a plain old atheist.
But not one of those asshole atheists that tells everyone that they're wrong about stuff. Unless your religious beliefs are actively harmful (which can be anything from snake handling to 'jesus will fix it when he comes back, let's pollute some more'), or you're trying to cram it down my throat, I keep my yap shut. Otherwise, I'm pretty good at beating people over the head with their own theology.
