Maybe it is and maybe it isn't. Depends on the drunk and the consequences. I don't like a lot of things and I put up with them. I like to think of it as being a law-abiding citizen, but that's just one of my idiosyncracies.
If (or when) it becomes your problem, the person is breaking the law and then I wholeheartedly recommend that a severe penalty be meted out.
You're up in arms about booze and tobacco today Froufrou!
