Vaping isn't going anywhere. By doomed, I mean legitimized, mainstream, widely accepted. That chance came and went...
eCigs are easily way more mainstream now than they were in say 2011.
From vaper perspective, they aren't any less legitimate. And from non-vaper, not so politically aware people, they are more mainstream than they were just 4 years ago.
In shared reality, the only thing that has really happened since say 2011, is that you are forbidden to vape in more places than you would've been 4 years ago. Even then, I doubt most non-vapers know this, and thus you could, rather easily get away with vaping in pretty much all locations, unless you vaped in front of a security camera or staff/guard. But since 2011, every aspect of vaping (literally every aspect) has grown, and/or become more mainstream.
I don't see how they were ever going to be widely accepted with ANTZ rhetoric dominating world culture. I also don't believe you thought they ever would be. If I am mistaken about this, let me know of what period you are referring to.
It is nice to see that when you said doomed, you didn't mean doomed. You meant it won't be more widely accepted as long as pics of vape conventions look like a foggy day. Yet, there are vapers who would rather not be in a fogged up room, regardless of the reason. I wouldn't wish to, but also wouldn't hate to see it happen and would strongly prefer it be allowed to happen than not. But, I also prefer if you are going to have a vape convention, make sure ventilation in the room is great.
If 80 of us got together anywhere (including outdoors) people nearby would notice our presence and may dislike what they see. Yet, get 80 people of any type together and I'm thinking not everyone would look fondly on them congregating.
Get a thousand vapers together inside a space (indoors) that will just barely fit a thousand vapers and I really don't see the harm in what they are up to. Thus the "not widely accepted" thing is really just spinning the ANTZ rhetoric into emotional plea for there to be no vaping anywhere indoors.
And is why I'd like to see organizers of this event, despite errors they may have made, fight back. And I mean fight back hard.
The regulation they were up against is a big fat Fail.
