Likelihood for rape tied to menstrual cycle?

I think we can all agree that rape is bad. But apparently according to evolutionary biologists, a woman's reaction to rape depends on where she is in her menstrual cycle. Really?

Take that in for a minute.

Apparently women are genetically disposed to fighting back more against rape when they are ovulating, and less likely when they are at other times in their cycle. This seems like a slippery slope to me, and a justification for rape rather than what it is claiming to be, and evolutionary study. If we believe that rape happens for reasons other than the rapist being a rapist then how can we blame rapists that rape when a woman is ovulating. She is just in her most fertile period, and so he is just following his evolution, right?

Wrong.

 As human beings we have evolved a little something called reason. This means that unlike our ancestors, who probably did forcibly mate with their female counterparts we can CHOOSE NOT TO. That's right folks, rape is not a product of evolution at this point, but a choice that human beings make. There are lots of different reasons that people choose to rape other people (women do some raping too), but they all come down to a choice that a person makes. We have the ability, unlike other animals, to rise above our biology and instinct and make decisions. That is what makes us human. That is what makes us civilized. That is why we can exist. Human beings have by far the highest capacity for reason, and jugement.

All in all, I think we need to stop looking at weird biological reasons people rape, and instead look at the people themselves, and perhaps the culture surrounding them. I am not an expert on rape, but I do know that even though our cycles DO put off different pheremones, and DO (to a certain extent) change our physiology, biological processes probably have little to do with the act of rape, and certainly can't be used as a justification.
