I have converted a few, and educated many more, some strangers that I will never know if they took the plunge, but I do it sort of on the sly, like vaping around them when they are smoking and let THEM ask ME about it. Then it's in their court and they tend to be more receptive.
I sometimes vape very conspicuously in front of certain people, like employees standing out Pets Smart in the cold, I sidled right up beside them and started vaping. Suddenly, they were turned on to it and wanted all kinds of info. I vaped in the smoking area outside an airport right beside a co-pilot and two flight attendents. They had heard about it but never seen it, then they too wanted more info. Many other situations but all the same, I let them ask me.
Sometimes covert actions make a bigger impact. Some smokers are so used to all the negative stuff, they are instantly on the defensive and not receptive. Seems as if when I let THEM make the first move, it works better.
Vaping has been a wonderful adventure for me, and I have been analog free for over a year, but I found them on my own, quite by accident. I would have been very negative to the idea if someone had brought it to me, so I quite understand their issues. I, too, was rebellious about "my right to smoke", and I shunned all efforts by friends and loved ones to advise me. Finding PV's on my own put me in control and therefore it gave me the satisfaction of knowing I was doing it for ME !
My daughter, my sister, my brother, several friends and co-workers have been converted, but only after they saw what vaping has done for the most hard-core smoker they ever knew.
Just my opinion and what has worked for me.
