Atheists only vote please: Do absolute MORAL truths exist? Is Rape ALWAYS "wrong"?

[MJ the Skeptical]

I can think of a what-if situation of rape where the theist would probably admit it'd be moral to do so, like if Yahweh asked you to rape someone. But otherwise the scenarios would be rare and full of ultimatums, like raping the last female on Earth who refuses to get pregnant or something improbable like that. But in practice, I think everyone would agree rape is wrong but universal truth implies that no caveats can be made, there should always be some small wiggle room with morality. I think history has shown that a bit of wiggle room can get you to the next progressive step forward.
