I know it's really aggravating to hear all this garbage all the time, but just think of it as an Educational Moment. When someone says something ignorant about vaping, THEY HAVE OPENED THE DOOR, now all you have to do is give them the facts, before they escape! And as tempting as it surely is to do it huffily, if you do it with polite forthrightness, they will be more receptive. You do not have to accept rudeness or ignorance, and you do not need to increase either -- we should be educating everyone who opens their mouth to spew some garbage they "heard on the news" "read online" -- it's our only recourse, and we should use it to the hilt!
