I don’t see smoking bans as fascism. I equate someone smoking in public with someone carrying a beaker with a contagious deadly disease in public. Second-hand smoke can have horrible effects on a person’s health. There are studies showing links to breast cancer, and I’m certain that there’ll be more studies linking other ailments to second-hand smoke soon.
Smoking is not the same thing as drinking, or reading, or speaking, or any other activity. Smoking pollutes not just the smoker’s lungs, but the lungs of people sitting in the vicinity of the smoker.
If someone can come up with a device that keeps all of the smoke and particulates with the person smoking, then I won’t have a problem. Until then, I definitely believe we need to ban smoking in all public areas.
