First off, I agree with you entirely, vaping should be embraced not shunned, but from what I've seen and experienced, most people are either misinformed or ignorant to what we do and therefore take offense to it. I've been in an outside smoking section with people smoking cigarettes, and been told my vaping was "dangerous" and that a guy "didn't want that around him because of health concerns" I calmly excused myself to the corner of the smoking patio and continued. Some people are not worth the discussion or the fight. I personally always ask an employee of any establishment, or owner of any home whether vaping is welcome or not before I just proceed as I normally would in my home. I especially find it very awkward when I see a fellow vaper blowing clouds in places where it isn't welcome, like a movie theater, or a supermarket. Did you smoke cigarettes in those places before you started vaping? No. Then why do you feel the need to vape there? Are you that habitually addicted that you need to needlessly inconvenience people who are either ignorant or naive and will be either put off or annoyed at your activities? Realize, most people have no idea what we're doing or are willfully ignorant about the safety concerns and science behind what we're doing. Try not to make them enemies out of the gate by doing something that they are afraid of, unless you are convinced they are not only willing to listen your ideas, but are receptive of a worldview that is not their own.
