I hate this question. Seriously? You are asking an atheist why she hates a god. Those who don’t see the ridiculousness of such a question are incomprehensibly thick headed.
An atheist, by definition, is someone who does not believe in the existence of deities. Atheism is not a religion, it is a state of being. In just the way that I am brown, I am atheist. I don’t believe I am brown. I know I am brown. I reject any assertions I am not brown (unless, of course, you are calling me some fancy synonymic word for brown). In the same way, I don’t believe I am atheist. I am atheist. Atheism is not a belief or a religion. Atheism is the rejection of the existence of deity in exchange for an evidence-based existence.
Atheism is NOT believing that there is no god. Here is an analogy. I don’t believe there is no god in the way I believe I will make it to work on time Monday. Believing I can make it to work on time implies that I also believe there is a chance I could be late. In that case, the logical thing to do would be to wake up and leave the house earlier than usual.
But a person who believes no god exists also may believe there is a chance a god may exist. That is agnosticism at best. I am NOT agnostic. I am an atheist. I know there are no gods. There is zero evidence of any deity. Therefore I reject the hypothesis altogether.
So why would you ask an atheist why they are mad at something he or she does not believe even exists? That’s like asking me why I am afraid of gryphons. It’s a completely illogical question because GRYPHONS DO NOT EXIST!
Seriously. Stupidest question ever.
