"genuine victims"
Nice.
The drinking argument is a bit tedious to be honest. You don't have to be physically unconscious in order to be unable to consent. If you are still standing, staggering about, but have no idea what the hell is going on, and barely able to string a sentence together, then you cannot consent.
I find it pretty creepy that anyone needs that explaining to them in the year 2015.
Someone posted the "tea" cartoon thing, which is a really good analogy as well.
You might want to take an actual look at the actual conviction rates for rape cases before getting on your high horse about "fake rape claims" or "she only said it was rape because she regretted it the next day".
You are right that rape cases will very often be a case of one person's word against the others. However, from a statistical, and a societal point of view, the law and society in general overwhelmingly side with the alleged attacker over the alleged victim.
