I tried for years to understand why smokers didn't organize. It may have to do with the demographics (more low-income, less educated smokers than the general population), or that the move to ban smoking started later than other movements, like gun control.
About 24% of the adult population smokes. That's a lot of people, probably close to the number that own guns. The public doesn't usually see guns being used, though, so they may not be so readily inclined to ban them. Most understand that there's a right to own them, even if they don't.
With smoking, while most people will agree in principle that people have a right to smoke, when it's in their faces it's a different matter. So the social disapproval may discourage smokers from organizing. I don't know.
It's refreshing to see establishments stand up to governments, although it never lasts.
