Plus, beyond my anecdote, the guy above posted research. Do we not believe in science anymore?
You are confusing posting a link with winning an argument. The problem is people have fundamental moral and legal disagreement about what constitutes consent with poster asserting it has to do with ability to make decisions and others including lawmakers in multiple states holding it rests in not being sufficiently impaired to severely degrade ones decision making ability.
It's impossible for the posters link to resolve this divergent understanding.
People's entire lives are derailed when they drink and get in a car and get caught for a DUI. The fact that we prosecute people, fine them amounts greater than some people's entire savings, throw them in jail, make them loose their jobs... For deciding to get into a car after 5 drinks. But if you decide to sleep with someone after 5 drinks, you were taken advantage of and that person should be prosecuted. In one case we give no sympathy for being drunk, and in the other we treat you like a child.
