"Fundie" is a universal slur against fundamentalists. It is used by the non-fundie right, left and center to describe those folks who not only wear their religions on their sleeves but feel everyone else on the planet needs to believe exactly the same way they do.
As for you being an atheist, your postings speak louder than your claims. You take the fundamentalist Christian side in all arguments, including creationism (why would an atheist believe in creationism?). It is pathetically obvious to everyone more intelligent than a retarded monkey that you are no atheist.
It is a leftist's last resort in argument... (I love it when they throw it at me, because I am an atheist.)
Your only purpose here is to bash the Christians and the Jews, many of whom are my friends. The Christians are really more of a politically correct proxy for your hatred of Jews. (I have more Jewish friends than Christian friends.)
