You do realize that there are different levels of drunkenness right
Literally re-read what I said.
So a person who drank one beer can not consent anymore, is that what you are telling me?
If the person can’t handle the beer then it cannot consent. If you’re sober and they’re drunk then you are raping them.
There’s 2 questions that must be asked in these situation
did she consent to it before being drunk?
is she capable of still understanding what’s going on and guve/remove consent?
If the answer to any one of these is “no”, “wellll”, “idk”, “I think/guess so”, or anything other than a very clear yes then she can’t consent. And when in doubt, assume the answer is no.
