The reality is that we cannot control people. These devices exist, and people will use them how they want. I think it's great that smokers of tobacco can quit cigarettes, and I want the same for people who smoke other things. That is just my opinion. I don't worry too much about what the general public thinks. I don't agree with the general American public on most things. I want vaping to be seen in a positive light as well, but I don't think pretending ecigs can't be used for other substances will help. Vaporizers vape lots of stuff. And they can help lots of people.
Again, your personal opinions and I respect them. However unfortunate, we as vapers have to be a bit concerned about how the general public perceives vaping. Remember what happened to cigarettes? Remember how it was perceived as "cool" to smoke in the 50's and 60's? Then what happened when the perception changed? It was banned every place. Even in outdoor stadiums and arenas. Now I'm not comparing the two. Smoking will kill you, vaping won't. Well, as far as we know anyway.
Ever see the movie "Gladiator"? Remember "Win the crowd, win your freedom"?
