THS has come the closest to answering the basic question. He's the only one who didn't make up ludicrious arguments or build silly straw men and thrash about.
He listed possible health benefits of moderate consumption and provided links. I can work with that.
It remains my conention that the miniscule benefits portrayed in those articles are overshadowed completely by the negative impact and influence of alcohol, but I can at least give credibility to his position.
The rest of you? Christ. Whiff, whiff, whiff, whiff, whiff, whiff, whiff....
Here's the problem that I see. You don't want to stick to one argument. When someone appropriately addresses one, you switch to the other and make yourself a moving target. Of course we're going to whiff when someone snatches the ball away before it gets to home plate.
The two arguments that you keep flip-flopping between are A.) Alcohol has no benefit, and B.) Alcohol harms people other than those who consume it. When we address A, you cite B. When we handle B, you revert back to A and claim we never addressed it.
So, to address both at once:
Just because something has no ascertainable benefit does not mean that it should be made illegal or viewed as morally reprehensible. As I mentioned in my last post, a tasteless food void of any nutrition may have no benefit, but if someone wants to create and sell it, they should be able to do so. The fact that something has no benefit whatsoever does not mean that it should be banned by law. So the alleged absence of the ascertainable benefits of alcohol should have no effect on its legality.
This only leaves your other go-to argument, which is the dangerous effects of alcohol. Every example of alcohol's harmful effects to others that you've presented have required that the drinker make a choice after consuming alcohol. This has already been elaborated upon, but as mentioned above, you conveniently reverted back to your other stance in order to avoid addressing the issue of choice.
