I'm probably a loud and obnoxious vaper, but I was also a loud and obnoxious smoker.

And to clarify, since none of you actually knows me, I've always been respectful about non-smoking places and the rules others had for their own homes, but if someone tried to lecture me or comment negatively on my smoking, in a smoking area I would light up just to be perverse, and in a non-smoking area I'd excuse myself to have a smoke.
I do not now nor have I ever given a rat's ... about what people want to say about me behind my back. Friends won't, and the rest don't matter. At most, I might mention it to my boss in case he gets some odd reports from busy-bodies.
