Why is Genarlow Wilson in prison?

Interestingly, it appears we have a different attitude to drunken consent in the UK. At least the precedent in the linked case seems to suggest that. I was certainly always under the impression that as long as the girl wasn't unconscious, it's not rape, per se, in the eyes of the law.

High Court judge Justice Roderick Evans directed the jury to reach a not guilty verdict, on the basis that drunken consent is still consent.

I mean, even if drink drivers are utterly tanked, we hold them responsible for their actions, don't we?
