Speak first, cite later. The Christfag will without a doubt not read your sources, so you don't have to worry about the credibility of anything you post on the internet, especially not whenever they promote the noble cause of atheism! Why would they? It's not like atheists are capable of lying.
Atheists are not nearly as stupid as Christfags. Studies pasted on
rationalthinkingfortherationalmindsrational.com have consistently shown that atheists are smarter than Christfags. One telephone survey from Pew Research that was conducted to the youngest male living in American houses (even though atheism is found in younger people who may or may not possess technology to reference the correct answers) that resulted in a conclusion that atheists know about religion more than theists! In addition, (niggers who happen to be) Christfags are more likely to be jailed than atheists, so atheists are more moral (because everything that happens to be illegal is moral, and vice versa, right?).
