People should be allowed to smoke, if they so choose.
People should be allowed to smoke in public, if they so choose.
People who go into casinos, bars, poll halls, strip joints, juke joints, etc. know they will encounter smoking there and just have to deal with it, like grown ups do. It would be ludicrous for a non-smoker to go into such places and demand to be accomodated by everyone else.
But, smokers who willfully light up in confined spaces (or in other public places where they know their smoke is unwelcome) because they are under the bizarre delusion that their "right" to smoke trumps everyone else's right to breath are rude a-holes and deserve to be called on it.
Like I said: Simple human courtesy. Funny that should be so controversial.
