Bumper Stickers About God

I'd like to know what makes bill board and bumper sticker writers think they know what's going on in a god's head -any god, not just the Christian one, though most of what I see is about that one.

I mean, driving down the road at any given time, you'll see at least one bill board or bumper sticker that's telling you something "God" says, wants, does, or believes. How did the person who wrote that know? Are they a direct conduit of "God's" thoughts/emotions?

Today, on my way home, I saw a bumper sticker that read "God doesn't believe in atheists." OK, now. First, how do you know what "God" believes? Did he tell you? Second, here's a pretty standard definition of the term "atheist": One who disbelieves or denies the existence of God or gods. So, if "God" doesn't believe in atheists, that means he thinks everyone believes in him. Sure they do - that's why there are so many atheists hanging around. This "God" fellow has a few issues if that's the case. I think he needs some therapy. I'll send Gaia over to talk to him about it. Or maybe Buddha or Allah. Or how about Zeus or Odin? Lillith, maybe? Hera? Osiris? Can I stop now? Do you get the point?

Really, people. If every god says they're the only one, or the only right one, which one's wrong? Can we all PUH-LEASE stop stomping all over everyone else's beliefs? Or, at the very least, can we all please not get all huffy and self-righteous whenever someone says "I don't believe the same thing you believe?" It doesn't mean there's anything wrong with what you think, so stop getting defensive. For goodness' sake, people, just accept that there are differences in thinking and move on and stop trying to convert everyone into YOUR mindset. It's just silly. You should all just believe what I believe and be quiet.
