I am not a drinker nor am I a smoker. I accept placing limits like time limits for driving, flying models or full size, or operating any kind of boat before after or while drinking. Anything where operating under the influence endangers other people.
I accept placing limits on smoking in public places. It only makes intelligent sense.
By non-drinker, I mean I don't go out drinking on my own, and I don't have any alcoholic beverage in my house. I do occassionaly have some beer or wine when I'm with other people, especially on business trips. It seems to be expected. Better class people don't have any problem with my drinking water or soft drinks, but I've been out with (Small) businessmen who seemed to be threatened by non-drinkers. Some drinking people become very hostile in this situation.
