You need to realize that we are dealing with plenty of ignorant and stupid people as so many reports on ecigs show.
Ignorance can be cured with the liberal application of facts. Unfortunately, there's no cure for stupidity.
I get what you're saying. The deal is, non-smokers who start vaping will surely be telling friends that it's not addictive, giving them info on the ingredients used, etc, just like former smokers (and those in transition, like myself) are educating those around us. Some will listen to the facts, and others will prove that they're stupid rather than ignorant. Anyone who is willing to listen to facts will understand the distinction regardless of whether or not the person in question has ever been a smoker.
And as for the stupid people, *shrug* we're kind of stuck with them. But I won't base decisions on what they think, or ask others to do so. And to people like that, and those who *don't* believe in people making their own decisions, their minds will be made up the first time they hear about PVs, regardless of who's doing the vaping.
