You seems to be saying that since the normal respiration and vaping are equal in the sense that we have no way of knowing what's being put into the air, then the 2 activities should enjoy the same privilege.
I am suggesting that, yes.
Yet, I do believe we have a way of understanding what both activities are putting into the air for others to breathe and that in vast majority of cases, it is relatively harmless on both counts. That we know this from science. We might not be 100% certain, but at that standard, there is nothing earthly that meets that criteria.
To that, Ill say that even if we agree that vaping and breathing are the same (which I dont agree), still vaping produces clouds of vapor that normal breathing doesnt. Clouds of vapor is a source of annoyance to non-vapers in general. My wife gets annoyed when I vape too close to her in the house and so I refrain from doing so. I dont look at it as conceding to anything, instead I look at as being considerate to her.
Additionally, as I mentioned, one cannot choose not to breathe while a vaper can choose not to vape.
But if the exhaled breathing thing was carried forth with courtesy being prime factor, we would all wear various forms of mouth filters. A simple mask or one that is elaborate. Either way, we would seek to do this if courtesy was prime. That we don't, and instead just breath willy nilly into the air, and just trust the overwhelming anecdotal evidence says a lot, I believe, in what we consider rude and a matter of respect/courtesy.
One can choose to have a filter on their mouth at most, if not all times. Assuming we cannot vape, eat or drink in public, then there really ought to be no reason given as to why this couldn't occur, unless we are just resorting to idea of, 'exhaled air isn't that big of a deal.'
The difference is that breathing is a normal, regular bodily function which all living human being have to do while vaping is extracurricular. If you are sick and you dont afford people around you some considerations, then you are rude. If you dont know that you are sick or that you dont know what exactly you are exhaling at any particular moment, we cant flaw you for that b/c you are just doing something normal and regular. On the hand, vaporing is extracurricular and that you do have control over it.
Again, my mouth filter thing noted above presents something I don't think you considered when writing all this. All people could wear a mouth filter and thus minimize / eliminate chance of air borne items being passed along from their exhaled air.
Also, people who are sick in pretty much my entire life will balance it out with 'must go to work' or must do some activity that they committed to. If I'm just starting to get a cold or just getting over one, I'm still carrying, but might feel good enough to be out and about. Even if I weren't feeling well enough, there would be the societal pressure of 'must work if able to' and so all that is in play with what we are discussing. I've also seen enough people in my life who are sick, go to work, and are treated as heroic for doing so. The opposite of being rude, they are persevering and not letting a little cold hold them back.
If the argument is:
It is unreasonable for you to ask me to refrain from vaping in public when god-only-knows what you are polluting my air and poisoning me with when you breathe out in normal respiration. So, if you are allowed to breathe, I should be allowed to vape.
Then one can use the same argument to say:
It is unreasonable for you to ask me to refrain from SMOKING in public when god-only-knows what you are polluting my air and poisoning me with when you breathe out in normal respiration. So, if you are allowed to breathe, I should be allowed to vape.
As a matter of fact, this argument was used by some smokers during the introduction of indoor smoking ban! It didnt make sense when applied to SMOKING and it doesnt make sense when applied to vaping.
With smoking, it was the scientific research that did it in, more so than the annoyance factor. And the research was manipulated, which is perhaps a discussion for another thread. But we have scientific research about what people are generally exhaling and research about what people exhale in the form of SHV. We don't have 100% certainty around any of these things (or really anything). But many of us know that at one point smoking was generally accepted in almost all public places, and now is accepted in almost no place, including own property. I know of smokers who will not smoke in their own place. I attribute that to the scientific research that has lead to a brainwashing of sorts.
With vaping the research has been conducted. It may not be umpteen hundred studies, but coupled with the anecdotal evidence, it is comparable to breathing exhaled air, and not with smoking. A key aspect with smoking and the annoyance factor, I believe, is the lingering effect. Otherwise, we would be allowed to still have designated smoking areas, especially as ventilation systems are able to make it so no 'particles' would be present for non smokers. But because of the brainwashing, just the smell now is enough to send most people into a tizzy and treat it as if they were just exposed to contagious cancer. An expert scientist and doctor could be present, run tests, prove to them that the risk is insignificant, and still the person, based on smell alone would feel they are infected and they don't care what anyone says. With vaping, there is either no lingering effect or very little.
You are comparing mall, store, etc. music with a personal music player, etc. The difference is that mall, store, etc music are background sound just as an airplane flying by or the traffic noise on the road. You cannot control it and it would be unreasonable for me to ask you to control it. On the other hand, it is up to you entirely to choose to be rude and pump out loud music from your personal music player or to have a loud face-to-face or phone conversation. And its entirely up to you to be courteous and considerate and choose to use earphones in public or keep your voice at a reasonable level in public. The point is you HAVE the control over it.
I decided not to remove your bolding, but did want to include emphasis on the loud, cause you didn't go there before, but now you have.
Loud music is, based on research, understood to be harmful. And yet, there are clubs I've been in, and for sure concerts I've attended, where music was obnoxiously loud.
As music is all around us, it is similar to vaping, but I'd actually say normal volume music is comparable to average vaping experience in public. If vaper is taking a puff, walking right up to someone and intentionally exhaling inches from nostril of stranger, that would be akin to the loud music thing. Otherwise, average vaping is akin to background music, and is what I'd go with for this discussion.
And again, you do HAVE the control to filter your exhaled air. We could live in that world, and if we are being consistent with the vaping argument, we would move in that direction.
