No one is afraid of us. The truth is simply that social acceptance of recreational nicotine use has been on the decline for decades in America, and as nicotine users we are looked down upon.
This shouldn't be news to anyone, and it's not necessarily good or bad, it's human nature. Each culture dictates what drugs are socially acceptable to use, and in what context it is acceptable to use them. In America, caffeine is fine in flavored liquid form all the time. It's looked down upon slightly in pill, unflavored liquid, or edible forms, but as long as you don't make a big deal out of it it's fine. Alcohol is fine if you're in a group who is also drinking it, or if you are having two or fewer servings with a meal. It's looked down upon in pretty much any other setting. Other drugs are so socially unacceptable their names are censored here.
Nicotine was acceptable in smoked tobacco form for a long time, now it's become much less so. Cultures change. I do think there is the possibility of less dangerous nicotine use becoming socially acceptable thanks to the e-cig, but I'm not sure that's even what most of us here want (socially acceptable will mean more people will do it, not to stop smoking, but because it's awesome. Which it is.) Currently society is trying to stamp out recreational nicotine use period, which again isn't good or bad, it's just what it is, so if e-cigs are going to survive the case needs to be made that they are a less dangerous alternative to smoking -- it's not about discrimination or equal rights or whatever (those arguments will lose), it's about harm reduction.
