As quite a heavy drinker, no I don't have a problem with it. As to the whole violence issue, I have been drinking heavily and regularly for years now, I have never once gotten into a fight, had an illicit sexual encounter, or driven drunk. I have never harmed anybody else through my actions.
In fact, alcohol helped me to be sincere and think clearly at a time when I was having problems getting my emotions out verbally (A problem I still have.), so its beneficial.
The only harm I have ever done to myself is fall over and injure my leg, so I fail to see how it could be considered immoral.
