"an atheist tries to prove that God does not exist..."
Not true. Theists are the ones who should provide proof if they want to stop looking like a bunch of nutcases. They've been trying for thousands of years yet not ONE, not a SINGLE ONE has ever brought a proof that god does in fact exist. And the more we learn about life and the universe, the more people are gonna stop beleiving in those crazy stories (even though we'll never learn all there is to know). Face it, gods were created by cavemen who didn't understand anything of the world around them. That'S exactly why they created them: to explain stuff. We don't need that anymore (or at least some of us don't).
"if "God" is "Love"...
as i believe God to be...
atheism couldn't believe in any of the above..."
There is no god. Since atheists are capable of deep love (as well as hate, both are important), it is real love that comes from the heart. Christians only show hypocritical love because that's what they are told to do. Trying to love everyone can ONLY diminish the love that you should feel for those who deserve it.
You are a worthless sheep who worships an imaginary character because your life has no meaning. If you only feel love because that's what your favorite storybook tells you, you really are a dishonest, miserable and pitiful creature.
