I once pondered, pipe in hand, with a friend, if there were more assholes in the world or not, us observing some species of jerk akin to the 20/30 year olds Monbla is describing. We came to the conclusion that no, in fact, there is the exact same percentage per population of assholes, but there's two things going on: there's more people, and more easy opportunities for people to be assholes unhindered.
That said, I conclude it is not their wares, be they cigars, pipes or drink.
Tobacco does not fix the world, it is just a reward for those decent enough to partake in all it has to offer. So to these jerks who abuse it: they're getting theirs by never knowing what it is like to fully enjoy the full picture. Any look I give them is in pity. If they push the envelope and insist on conflict, I figure it is their way of feeling shame. I wouldn't want someone staring at me making a silly mistake with something I'm convinced I know, either. It's very uncomfortable. Out of respect, I usually leave, but sometimes it's appropriate to tell them to relax and not be rude.
There's an upside to more people on this rock: more opportunities to find good folks to smoke and drink around.
