Depends on the type. I agree that most alcoholic beverages are crap and that wine is overrated. But, taste and comfort. I don't have the same tastes as the next person, so I see no reason, unless they're assaulting me while wasted, to interfere with their destruction of their liver, if I don't know them. Life is too short for that sort of discomfort.
