Wow, that is awful. Try telling someone who's had a loved one killed or injured by a drunk driver that its not a serious crime. Oh, and I consider myself "normal", and have never driven drunk.
Driving over the legal limit does not = killing or injuring someone else. Driving over the speed limit kills many people as well, but not every person driving over the speed limit is a danger to kill others on the road. Its not simply a black and white, I am not arguing with the law but it is a fairly minor crime in many cases.
