It takes a certain level of inconsideration to sit there and cause other people to breathe smoke. How much would it impact someone, say yourself, to kill someone by inducing an Athsma attack on your lunch break?
Further, it's already the case that laws exist to make certain behaviors illegal for the very reason that they inconvenience other people, not because they cause harm. That includes being excessively noisy and producing foul odors in some cases, among many other things.
What I've learned today is that there are a lot of inconsiderate assholes on Hacker News. Be it out of general apathy of others or just sheer stupidity. I'd have argued the latter could not have been the case many months ago, but given the recent discussions and new posters, it seems to be a contender. Perhaps then, it is vogue to "care about others" when it's convenient (for instance, when it makes you look good or benefits you), but otherwise fuck other people, because "what I want to do is more important than your entire life".
And here I thought this wasn't /., reddit, or 4chan. Wrong.
