If you say you have a lack of belief in gods, you're a wimpy idiot. Magic god fairies are not real. Period.

atheism: 100% certain magical beings (Easter Bunny, Tooth Fairy, allah, god, zeus) are not real. 

atheism: An acceptance of reality. 

atheist: a normal person, not infected with the stupidity of religion. 

An idiot wrote "An atheist is a person that believes there is no God." 

Reality is not a belief. I'm certain the Easter Bunny is not real. That's not a belief. It's reality. Same thing for the moronic magic-god-fairy fantasy. Being certain this bullsh!t is not true is not a belief. It's reality. 

Another idiot wrote "So, atheism is a lack of belief in god." 

Only a wimp would write something like that. God fairies are not real. Period. Nobody says they have a lack of belief in the Easter Bunny. The childish god fantasy is no different from the Easter Bunny. It's not real. And anyone who isn't 100% certain these things are not real is an idiot.
