Regarding decency, respect and vaping where it is "appropriate."
In many many posts on this thread and others just like it, I see many vapers agreeing with position that vaping in enclosed spaces is simply not right. Or it is disrespectful, indecent, a nuisance, and working against the entire vaping community. I, as a pro-vaper, have a very tough time understanding this, but not impossible.
Many of these same people will also say something along lines of, 'not okay to vape in this building, and is why I go outside.' Which on a vaping forum, given what we all know about vaping, is rarely, if ever challenged. But, IMO, it needs to be challenged given again what OP is getting at. And it needs to be challenged with either the same or very similar arguments put forth, by vapers, against indoor public vaping.
For to the non-vaper, and for sure to the anti-vaper, it is disrespectful, rude and a public nuisance to vape outdoors. You say it is perfectly safe, but you know it isn't and there are studies out that don't equate to 'perfectly safe.' But taking out safety from the equation, it is still something that to some, looks like smoking. But all vapers know it isn't smoking, so let's take that out of the equation. It is still disrespectful and is arguably a public nuisance to vape outdoors in a public space. Or a private space outdoors that is a place of business where fellow members of the public could congregate. People who don't share your knowledge on how long your vapor lingers outdoors, and what exactly is in the vapor. It simply looks bad, looks like an addict getting their fix, and is disrespectful.
Perhaps you asked those near you, but unless willing to ask all those all around you, even if not in your immediate sight, then you are engaging in something just to be selfish. To enjoy what you want, regardless of who may come into that space.
Now, of course, myself as the pro-vaper that advocates for vape everywhere, I don't believe all of what I just wrote, nor do I feel it ought to apply to indoor spaces. Yet, I do really really wish to make the point that if vaping indoors is inherently indecent and/or disrespectful, then so is vaping outdoors, regardless of whether property owner allows it.
I further believe that a vaper who vapes indoors, and no one is around is being more respectful / decent than a vaper who vapes outdoors where there are perhaps several people around. But when we make blanket statements such as 'never okay to vape in a hospital, restaurant or theater,' I'm thinking we overlook the idea that the vaper might be the only person in a particular location in those enclosed spaces. And if vapor is theoretically lingering all the way from one side of the hospital to the other side of the hospital, then a) that's some pretty powerful vapor and b) it would be equally unwise to use that vapor outdoors, anywhere, because of just how far it could, theoretically linger.
Bottom line: from the anti-vaper's viewpoint, wherever you vape, it is indecent and disrespectful. There is no 'reasonable' place to vape and there is no appropriate place. You are (selfishly) making up places that you personally deem as okay. If your fellow vapers happen to agree with you on the appropriate places, goodie for you. Now go ask the non-vapers and anti-vapers if they agree and then come back and let's have the reasonable discussion on where it is always respectful and always appropriate to be vaping.
