I was a volunteer medic too. For many years. I'm pretty much zero-tolerance for drunk driving. But, I've seen a whole lotta chemically-altered people over the years, and I disagree with in "vino veritas". People under the influence say and do incredibly stupid things that they would never do or say under normal circumstances. So, is the drunk the "real" person? Not unless that's their normal state, in my opinion.
Alcohol in excess, like any bad habit, amplifies negative and destructive tendencies. That's why it's a bad habit. If it made people more loving and improved motor skills, it wouldn't be discouraged.
That said, it's obvious Mel Gibson has an opinion about Jews which does not correspond to the reality of the world situation. Then again, Mel's assessment of Jews is not far removed from what most of the UN apparently believes.
I'm always shocked how celebrities can keep drinking and not learn to manage their alcohol (getting arrested, being loud, etc). Most people learn that right away.
I partied when I was young, and I sure was a different person when drinking. But when I rarely get drunk these days, one would never know it. I am quite the same person except that I fall flat asleep by 9pm (instead of 9am).
I think you're misusing the word "REAL." Being drunk let's go of our inhibitions. Saying I HATE FUCKING JEWS is not something you would say in polite company...even though that's what you think. But when you're drunk..that filter is gone. So when we say "THE REAL" person comes out...it's the stuff that we think and would like to do in our hearts, but our natural society "filters" won't allow. I hope that was understandable.
