” But being judgmental towards smokers is thouhgtless and borders arrogance. no one appreciates it”
People are judgmental, as you put it, because the smoker is not only harming him/herself. We also have to breathe in the polluted environment that the smoker has filled with assorted toxins. In this equasion, the only thoughtless people tend to be those smokers who(bordering on arrogance) feel the sense of entitlement to smoke where and when they want, no matter whose lives are being affected by it. If one wishes to smoke, then perhaps he should get a helmet like the astronauts wear in space, and smoke while wearing it. At least he will be the only one breathing that foul stuff.
