There are those who do not know but claim to know. They tend to be theists. Atheists do not claim to know. They claim that nobody knows. This makes them right. And the theists? They're worse than just wrong: they're lying.
I believe this with all of my heart. In the end, only kindness matters. From Eve DeVinney if a person is hateful they cannot be Christian though they profess to be. Christianity is about love, compassion, forgiveness, understanding - never hate.
In your eyes yes, I am Atheist, since I do not believe in a creator, nor do I believe in a soul, nor do I believe in an eternity. In my eyes I am just Agnostic because it's really not that serious since no one has any proof of any of that anyway. There is no argument on my part to uphold.
