If you want to change the current environment, the only thing I can see to change it is to get the masses back on your side. The only way I see to get them back on your side is to reduce their exposure to current smoke and get them to believe smokers are doing everything possible to reduce that exposure.
My whole point is that is isn't the responsibility of smokers to protect non-smokers. Just as it isn't the responsibility of non-smokers to protect smokers from themselves.
Non-smokers, being the larger percentage that they are, are free to open non-smoking restaurants and bars and leave the smoke-filled businesses alone.
But they won't. Because it isn't about wanting smoke-free establishments. It's about dictating behavior, exercising control over others and banning smoking altogether, in a backhanded way.
