As I've stated previously, I took a proactive position from the start, letting folks know that I wasn't using e-cigarettes as a "quit smoking" tool (even though at the time I honestly didn't know if I would or wouldn't eventually drop them), but simply as a safer, cleaner nicotine delivery system. I've fine tuned that answer as I've gone along, and explain that for me I always have and still enjoy the ritual and ceremony of smoking, and now I have found a system of nicotine delivery that allows me to truly enjoy my addiction of choice, like others enjoy caffine, without all the carcinogens and additives that come with the burning cylinders. My delivery is always warm and sincere, and clearly not open for debate - I've only had to "defend" that position once by explaining I wasn't arguing a point, simply making a statement, and then distracted the inquisitor (a dear "love to debate things to death" sort) with a simple "asked and answered" and the introduction of a different unrelated topic. It's possible that someday I may choose to simply stop vaping, but having tried for over 30 years to give up cigarettes unsuccessfully, I honestly believe my current statement is true for the long term, and it works for me.
