Oh, I don't think that in any way calls for government involvement; it's more on the level of someone who doesn't shower or use deodorant for a couple day--a social faux pas, but not a crime.
As far as meetings go, I have tolerated the smells of various non-smokers and tolerated the disgusting (to me) stuff that some health-nuts and enviro/health/fitness whacko's insist on eating/drinking, and while I find it OFFENSIVE TO ME, I have yet to see masses of them attacked by smokers/others for their tastes.
No, but normal people do snicker about them behind their backs. :-)
Snickering behind their back would be GREAT for smokers, if that's what was going on today in reality.
It's the PC/Bandwagon-hoppers with the "in your face" attacks that have caused smokers to confront the accusers now, and that's too bad. Peaceful co-existence between smokers and non-smokers is sadly gone, as the assault on rights of individuals has been taken way out of bounds to the extent that LAWS against freedoms are being enacted, to the cheers of the anti-smoker fanatics.
