Personally, since I remember the anti smoking ANTZ beating up on smokers before there was vaping, I
try not to add to the negative comments about smokers, how they smell, etc.
It kinda worries me that some vapers may become as ANTZ- like as some of the smug holier than thou *ex smokers* who quit ---- actually I've kinda already seen shades of that happening. (yes, it's hard to NOT support smoking but still support the smoker, esp. when the smell does bother us now)
But the observation of just how uncomfortable cig smoke can make people surely makes me feel bad, in retrospect, for all the non-smokers who had to sit in offices, restaurants, sporting events, etc with us when we were smoking and before the indoor smoking laws were passed. A lot of times they got a lot of backlash for whining about it.......however, I'm sure it really did make their eyes hurt and their clothes smell.
I was the only smoker in my social circle (and now am the only vaper) but my friends were and still are always very generous-hearted about allowing me to do my thing (within reason).
