Why? Because you say so? How about we ease off the attitude. No one is forcing anyone into this discussion or out of it.
Look, I started what I thought might be a fun thing to kick around a little bit. I didn't realize the amount of collective sticks up rear-ends I'd find. None of us are in high school, OK? You don't have to drink to 'be cool'. On the flip side, because you might have a drink doesn't mean you have any penchant for drunken outbursts. Why does everything have to boil down to the lowest common denominator over the course of a simple discussion?
I think there may very well be some small health benefits to some alcohol consumption. I don't know a single person who drinks alcohol for it's medicinal purposes. In general, people drink for a relaxed feeling. It doesn't take much to do that and that's probably about the point of diminishing returns on the health front. For anyone, pro or con, to make some this to be some sort of moral quagmire is absurd.
