Those that are adamant non-smokers often believe wrongly that the mere hint of tobacco smoke will kill them, or injure them in some way, and consequently this thought process gives them the moral high ground to eliminate smoking and any visages of smoking from the community at large. The fact of the matter is that most smokers are polite; they don't deliberately blow smoke in your face, they don't deliberately go out of their way to annoy you by smoking, and most smokers are content to just be in a place where they can enjoy their cigarette break without any undue hassle, and/or to be in a place to which cigarette smoking is permitted as a matter of course. The fact of the matter is, most smokers are respectful and simply want to enjoy their cigarette, but the unjustified crusade against them never seems to stop.
The problem with the anti-smoking crusade is that not only do these crusaders refuse to share the road with smokers; their belief is that the road of life should not contain any smokers at all. Somehow, over time fanatical non-smokers have aggrandized to themselves the right to believe that they should make your personal decisions for you, and smoking is just one of those rights that they should decide for you. The bottom line is people would not smoke if they did not derive some sort of pleasure or comfort or stress relief or similar from smoking, and the decision to smoke or not to smoke should be left up to the individual and not to State agencies, killjoys, or annoying do-gooders.
Life is full of all types of people, to wit, some will give you their piece of mind without any prompting whatsoever, and some will take it further and insist that they have to control your life, without ever having the common decency to understand who and what you are and not really caring about that as long as you obey them. It is a fact, that we are individuals, and further that some individuals gravitate to certain things that might offend or bother other people, but that is their prerogative, that is their choice, and that is their lifestyle.
Certain people complain all day about smokers and how nasty and dirty that they are, but there are endless things to complain about. For instance, perhaps one doesn't like the smell of certain foods, or of your breath, or you have too much hair or not enough, or too much perfume, or you just smell bad, or you'rebow-legged, or your clothes don't fit right, or your accent is annoying, or your opinions are just plain wrong, and so on. Our civilization is based on the fact that each of us has the right to be ourselves and to live the life that we want to live, and unless somehow we are breaking a meaningful law, to just be.
The anti-smoking crusaders are really just a cover for busybodies that aren't satisfied with giving unsolicited advice and warnings, but want the arm of the law, to strike smokers down, all because they believe they know best and just want smokers to shut up or to crawl into a dark hole and die. The anti-smoking crusaders are control freaks, misguided, bigoted, prejudiced, destructive, and intolerant of the freedom of choice.
