So some believe. My conservative upbringing taught me to bend over backwards so as to not offend another without cause. So I do not smoke cigars inside or around those whom it bothers.
Courtesy is good in all things. The courtesy of a bar owner letting his patrons know if it is or is not a smoking establishment, for example. Nanny statism is bad news. Trans fats and sugar drinks are the next target for nanny staters. Oh, and the worst of all nanny-state trends is political correctness such as "hate speech" and "hate crimes", of course only enforced against whitey.
