That sounds like you are saying whatever happens to you while drunk - is YOUR fault because you chose to get drunk. I would not as that is pretty awkward and archaic thinking.
You're old enough to drink, and hopefully mature enough to know you are dumb while being drunk. There are consequences for bad decisions.
Now, that doesn't mean drunks deserve to be raped, but hey... maybe if you're around good friends or people you at least know it doesn't need to get to that scenario.
Statistically speaking, the majority of rape that does occur is by someone the victim knows. It is actually rare for an individual to be raped by a complete stranger. At least know what you are talking about, before making a baseless suggestion. Hey, it is the internet, where everyone has an opinion, regardless of how much they actually know about the topic. Also, the person who is raping you can lure you away from your good friends (friends can get seperated). If you are lacking your basic cognitive skills and someone takes advantage of that, they are definitely in the wrong.
@OP. The first scenario is definitely rape. The same rule applies for sales. Legally, you cannot make a point of sale to someone who is intoxicated, as this is taking advantage of that particular individual.
Just because you are intoxicated, does not mean you are asking for trouble to happen. Some people become intoxicated unintentionally, as the degree in which you can handle alcohol can actually very depending on your mood, health etc.
Even if you intended to get intoxicated, as you might be celebrating a promotion, graduation etc. does not mean someone should take advantage of you.
