@Lessifer long answer!
The fear of over regulation seems to be the driving force behind peoples perception of a reason for vaping.
In the average vapers mind regarding the public perception:
If people arent safe, they get hurt and vaping=bad
If people start using nicotine who wouldnt have before, then vaping=bad
If the flavors attract an adult, those same flavors will likely attract a minor, then vaping=bad
If your gear isnt the same as mine, then yours in unsafe, see item #1
Fear leads to anger, anger leads to hate, hate leads to...Suffering!
