Yeah, I'm done debating with you. I've studied the subject matter at hand fairly extensively, it's one of the reasons I stopped smoking, because I didn't want to harm my daughters, and none of the literature ever pointed towards any ill-health effects coming from passing near/through smoke outside, just the situations I pointed out. As Old Andy pointed out, you're much more likely to derive ill-health from car exhaust then you are Second-Hand smoke outside. Either point out the literature you've read(and it needs to have scientific studies that back it or I'm not believing it) that shows your point, or drop it, because the burden of proof is on you since you're the one making such a big deal out of this.
On another note, I do however agree that is quite rude to smoke directly in front of an entranceway to a building. Many places either have designated smoking areas off to the side for smokers, or just don't allow it near them, and it is an impolite thing to disregard those rules and smoke where people can't avoid it. I just dislike people constantly bashing on smokers all the freaking time, every-time I see an Ad on TV talking about how god awful the tobacco companies are, it makes me want to pull my damn hair out.
Yeah, tobacco companies hiring researchers to conduct biased, unscientific studies to conclude cigarette are a-ok to smoke and breathe in second hand, which has long been determined a detriment to people's health.. I can't think of a reason someone might want to bash the tobacco industry.
I've already linked to three specific articles earlier on, so the burden of proof is not upon me to keep citing for those who came late to the debate and didn't read the topic.
I'd go on about cars once again but I'm not really into repeating myself.
