Yup, by its very definition no less.
Wow. It gets better, and better. You just said by it's very definition it is the opposite of having a belief. This is now the most asinine thing I have read all day. You are now saying that Atheists have no beliefs? If by it's very definition like you stated "it is the opposite of having a belief", then they "Atheists" have no beliefs according to your silly made up definition. I couldn't write this type of humor if I tried, you are such a natural at being stupid.
