Giok, now I'm riddled with guilt for failing to resist the chance to score a cheap point! I knew well enough that the parallel with smoking wasn't fair, because smoking directly affects a non-smoking majority. It just seemed fair game at the time. Not for the first time, I cringed a bit to read in the cold light of day what I'd scribbled under cover of darkness. I would normally keep my head down and hope others wouldn't notice, but your response was too gallant to ignore.
