I think if we lead/allow people to believe misinformation or partial information, we're setting ourselves up. If I say, "water-based vapor" knowing that they'll hear "water vapor", I may make my own life easier in the short term, but I do a social disservice to the rest of the world. It sets things up for headlines like "E_CIGARETTE "WATER VAPOR" FOUND TO CONTAIN PROPYLENE GLYCOL!!!"
I would love to be able to vape anywhere, anytime I choose. That would make MY life easier. But I'm not willing to buy that at the expense of the eventual effects of soft-pedaling the truth, skirting reality, sins of omission, sugar-coating, whatever you want to call it. For me, it's not enough to say, "They don't really want to know," when the truth is, "I don't want them to object to what I'm doing, so this is all I am going to tell them."
Full disclosure is what separates us from weasely corporate interests, innit?
