It seems we got to the root cause of our disagreement. I do not think you suffer from a personality change when drunk. Yes, you might do things that are criminal when black out drunk, I can agree to that. But not because your personality changed. Because natural tendencies you usually over write with reason are not over written -your reason is gone for the moment.
So if you are a little greedy and materialistic, you might steal. If you have a short fuse, you might get into a fight. If you are a bit of a dare devil, you decide you could totally free climb the side of that building.
But you won’t go against your personality. You wouldn’t cheer for the rival football team. You wouldn’t pledge money to Trump if you’ve been feeling the Bern. And you wouldn’t take advantage of a person if you respect them.
