My father was a smoker, until his near-fatal stroke at the age of 53 which has left him permanently disabled and according to the doctors was due to smoking not cholesterol. Admittedly I neither like him much nor respect him, anymore. My mother, whom I both like and respect, smoked all my life until 5-6 years ago, when she quit (mainly to save money, not from any road to Damascus conversion). So no, smoking is not a sigil or stupidity or bastardliness - but getting on a high horse that one's right to smoke wherever one pleases, counting on people's natural politeness or shyness to let one get away with it and believe it's no big deal and non-smokers are just being arsy is definitely on the wrong end of the bastardliness spectrum.
