A militant atheist who has taken his/her lack of belief in a new direction, becoming an advocate of atheism. They tend to believe that religion is the worst thing the world has seen, the cause of most problems (racism/sexism/terrorism/homophobia/war) even though it may only play a small role, but tend to think of it as a disease. They tend to make stereotypes involving religious people (meaning that believers are racists, sexists, homophobes, and terrorists), and stereotype themselves as being intellectuals (along with throwing rationality and reason into it). They are usually insecure about being an atheist, or have no major distinguishable characteristics in their personality, which is the reason that they are militant regarding religious skepticism. Will be unable to accept differing beliefs on the Internet, but disregard this in real life due because they would become extremely hated.
May be considered a "bad atheist", although a technical term would be anti-theist.
Not to be confused with an atheist
Christian: "Hey, I just got back from church."
New Atheist: "You believe in God? You know that's just a fairytale for people afraid of death, right?"
Christian: "I'm not really afraid of death, but I believe that afterwards we lead onto an afterlife."
New Atheist: (to himself) "It pisses me off so much that religion STILL exists."
