So many heresies, so little time

I have an opportunity to test an interesting opinion/testing software program. Just to make life interesting, I thought I might give the topic of "What kind of a heretic are you?" a try.

So, help me out...and come on down. What is your favorite heretical concept? Not necessarily that you agree with it, of course. And do say why you find it interesting, just to help me with my homework. Anything from the first century to Jesus-as-Rambo is up for consideration.

(It was either this, or a listing of my favorite brands of fair-trade certified coffees. You can comment on that if you aren't in the mood for heresy).
