I was re-reading this post, thinking about the whole "SHS kills" campaign that pretty much everyone has bought into -- except yourself, of course.
(and me too, to some extent) I think the problem is that there actually is *some* risk, particularly to *some* people, and they have taken this very slender factoid and blown it completely out of proportion to the *actual* risk to *most* people. Many, if not most of us, have known someone who actually was adversely affected just by regular exposure to tobacco smoke, and we've been encouraged to think that the adverse effect is *always* true for *everyone* -- which, if that were true, probably none of us over 40 would have even been born, because our parents' and grandparents' generations were very high in smokers and thus also high in those exposed to SHS.
There is a good reason I smoked around my son till he was 9 -- because almost every adult in my life, when I was a child, smoked -- and they didn't run outside to do it, either -- they sat right in their own living room or at their own kitchen table and smoked their numerous cigarettes -- to me, it was a very rare thing to walk into a bldg where there was no smoking -- my aunt's apartment was the only place i knew like that, because she never smoked; her place smelled like dried eucalyptus.
But restaurants, grocery stores, schools, doctor's offices, hospitals, even churches in the offices and vestibules. Nobody had a cow about it; it was just a regular part of life. Lots of people smoked, and those who didn't needed to be polite, or have a legitimate medical reason why it was unwise/unkind to smoke around them -- my eldest uncle's emphysema, for example. But mostly the smokers were polite; it was very common to hear "Mind if I smoke?" and if someone really objected, most people were polite enough to refrain.
The world has changed, and in so many ways, not for the better.
