I am not trying to be rude, but you have aparently not spent time dealing with some in the anti-smoking" groups.
Many of these people are certifiably "nuts." There are well known ones that are paid too make comments along the line of looking forward to smoking parents will be jailed and their children removed and placed in state care (had that said to me just recently), others are looking forward to the day they can plow under tobacco farmers crops while the farmer and family are watching, that tobacco company executives should be shot repeatedly with small caliber weapons in the region below their belts in order to suffer a slow painful death. But the best I believe was the one that said a woman who chooses to smoke while pregnant should have an abortion because the child would be better off never being born than being born to such a person.
Non-smokers, I have no problems with and will abide any request of not smoking in their proximity that is reasonable. Anti-smokers are an entirely different breed of character.
