That is a good question.
I believe there are two different types of alcoholics. Daily drinkers and binge drinkers. Some alcoholics drink all day long, every day, of every week. Then there are the classic binge drinkers. They power down as much as they can on a Friday and Saturday night. I don't think the classic binge drinker is seen as an alcoholic by the general public. Alcoholism is an addiction. Binge drinkers are addicted to getting drunk in a social setting. I do think that is a form of alcoholism.
