I get that you're having a bit of fun with your comment, but I can't help but wonder if many "militant" atheists are labeling themselves as atheists simply to get reactions.
There are many that really seem to enjoy being atheist for the sole reason of pissing off religious people. Like I'm talking about the /r/atheism type people, the "Facebook Warriors" who feel the need to "educate" everyone with facts/logic whenever someone dare thanks God on their own Facebook page or something equally trivial. And then I think everyone else who is just simply and atheist but doesn't care to really talk to people about it ends up grimmacing everytime people from the militant camp open their mouths.
Interesting parallels here (I think) between atheism and homosexuality, re: "militant".
