Let's call this your only chance

Yeah, no shit. I'm sure even the Republicans understand that. Alcohol impairs judgment, yet it's more like hypnotism; you're more likely to do things you wouldn't normally do, but you don't do anything you're extremely opposed to.

By your argument, men who rape women while drunk are not responsible for their actions and consequently should not be punished.

No, because consent to having something done to you isn't the same thing as responsibility for what you do.

And what if two drunk people having sex? Are they both raping each other? And what about the thousands of people who willingly have sex while drunk? To call that rape would be degrading to the tragedy and seriousness of rape.
