To me the question comes down to freedom and rights. The smoker wants the freedom and right to smoke. The non-smoker wants the freedom and right not to be in its vicinity. The two things cannot co-exist. In my opinion the person performing the action, be it an addiction or not, is infracting on the other persons' rights and freedom to not breath in the smoke.
Though there may be a few smokers who are considerate I'd bet big that they are in the vast minority.
I don't believe conscientious smokers are in the minority. All my buddies who smoke are aware that not everyone likes it, and like me, try to avoid those situations (I smoke to relax for a sec, not to get myself in arguments) But I also believe that some non-smokers have a giant chip on their shoulders in relation to smokers, and take it personally. If your gonna confine smokers to certain areas, don't get upset if you go on their turf and catch a whiff. Most of the country is now non-indoor smoking. I understand this, and I agree, it can be distracting/uncomfortable/nauseating. But I think the way people treat people smoking outside is just ridiculous, and at this point, you can just get over yourselves. We aren't hurting a d@mn thing.
