Earlier quoted context omitted.
It always amazes me when smokers try to paint themselves as martyrs, because we keep trying to get them to stop exposing other people to their smoke. I'm sure it's inconvenient that you have to go outside and away from the doors to enjoy your habit, but if that's a problem then maybe you should have picked one that doesn't pollute so much.
Apart from the initial time they chose to smoke (and bear in mind it quite possibly might of been in a time where the health risks were far more contested) it's interesting that you suggest an addiction to be a choice.
You're right, some people got addicted back when it was cool. But there aren't a lot of those people around these days. (Most of them have either died from the habit or quit it.) Of those who remain, I do feel sorry for them. But they're not generally the ones I see complaining and trying to be a martyr.
Plus if you're addicted that badly, how about using the patch as a substitute? Or smoke in private. Just because you have an addiction doesn't mean you shouldn't be responsible for satisfying it in a way that doesn't impact other people.
