Anyone who doesn't smoke. Usually very arrogent and ignorant in their opinion. Generally, they make it a hobby to be as ignorant as possible to smokers. Tend to believe they're superior and better than smokers. Also, a majority have never smoked therefore can not understand it from a smokers point of view, but their arrogence blinds them of this. Their arrogence also blinds of the fact that the air in any decent sized city isn't much cleaner.
