In this thread, given what OP has conveyed, it applies 100%. Outside of this thread, who knows? IMO, outside of this thread, I think vapers are allowing a whole lot of teeny tiny 'safety issues' to lead them on a path that equates to vaper's guilt. I believe some vapers are self determining that vapor is rather harmful (according to their reasoning) and advocating for things that feeds right into what FDA was going for, or likely will continue to go for.
Fast forward to a time where plausible majority of vapers are convinced that vapor contains some very harmful stuff, and they feel guilty about doing it (knowing they are harming themselves). Around this time, assuming the previous sentence holds true, I imagine that regardless of what science says, that these same vapers will be convinced that no one should ever vape around anyone else, in any situation, other than outdoors, because the belief will be that it is harming other people. Thus the vaper's guilt meme will be firmly established.
That we already see some of this in today's vape world is not very promising. That the overly concerned crowd does receive flak from within the vaping community, pleases me. Especially considering their use of science is routinely based on junk.
