As an nonsmoker I rarely ever venture into areas where there's cigarette smoke, I simply don't enjoy the smell. But I could also say the same for many other smells, such as fried foods, etc.
I will agree that smoking is dangerous, but I also accept that many other activities also come with risks, small and great.
The hypocrisy: The chance of an eighteen year old smoker dying from smoking within a year is trivial compared with the chance of an eighteen year old athlete dying on the sports or practice fields within a year. Yet no one is trying to put a stop to those activities - yet, anyway.
Once the smoking ban has been secured, do not think for a moment that the anti-smoking campaigners will simply go home with this one victory. No, these do-gooders will soon look for the next activity to prohibit with the force of government. These folks are not in this for the good of all, they are simply in this to control society.
Revolutions of virtue follow the pattern of the French Revolution where a Reign of Terror follows the early victories. You see, in some eyes, virtue is to be forced on everyone - at least virtue as defined by those empowered by victory.
As CS Lewis noted decades ago, the virtuous never sleep since they always believe that the non-virtuous (as defined by the virtuous) need government interventions in order to live the good life, and it's the sole function of the virtuous to find any aspect of the lives of the non-virtuous that requires intervention. This is a heavy burden that sleep only fails.
Watch out for these people...
