“Frumnotyeshivish – I don’t think smokers don’t believe that it’s dangerous”
You are IMO fooling yourself if you really believe that. Maybe SOME smokers actually are fully cognizant of what they’re doing, and are willing to take their chances, but the vast majority of smokers whom I have seen interviewed about their “rights,” pooh pooh the whole notion (and that is part of the addiction). They will rationalize it every which way they can, to prove to themselves (certainly not to the rest of us), that there is no harm either to themselves or to the rest of the world around them.
YES, they ARE polluting the air that we non-smokers have to breathe. There are many, many types of air pollution. Smoking should not have to be one of them. Let them smoke in a bubble, if they wish, and breathe their own stale, stinking, recycled air as much as they wish. I won’t say a word. (though I hope they wise up sooner than later. Emphysema or lung cancer are not pretty ways to die).
