My theory is that when one's value appear to change under the influence of alcohol (or other mind-altering substances) it is when those values exist only because of the fear of social penalties. As when someone obeys a social custom because the community says it is what is right, but it is not personally believed to be morally right.

For example: You never raise your voice or use profanity in public restaurant, even if a sloppy waiter spills a drink on you. However, if it were to happen after enough alcohol you might yell at the waiter cursing them in every foul word in your vocabulary. And yet, because you truly abhor physical violence you would not even consider striking them and would be very uncomfortable witnessing someone else doing so, regardless of how drunk you were.
