Personally - and maybe this is just me - I am more sketched out by people who WON'T allow any "drug talk".
There is really only one substance that is ever mentioned or parodied in the vaping community; you know the one I mean. That substance and the culture surrounding it has permeated every aspect of our society: cheech & chong, snoop dogg, michael phelps, raggae, college, baby boomers, hippies... most popular music is associated with this substance - it has its own genre of comedy films, many of which are very popular in the mainstream - it has TV shows now too, and is legal/decriminalized in some form in 18 states. Nobody bats an eye, except the most hardcore of traditionalists, and if anyone thinks those people will ever accept vaping I have a bridge in Brooklyn to sell you.
On a related note, many vendors sell alcohol-themed flavors: bourbon this, cognac that, even "Budweiser". Alcohol is a drug. Alcohol is illegal to some vapers (18-20y/o in the US). Why aren't we worried about folks claiming e-cigs will get you drunk? Why aren't we afraid that vaping will be grouped in with some seedy alcoholic subculture?
Censorship sketches me out. What are we hiding? We have nothing to hide, or to fear. North Korea uses censorship, because they have terrible things to hide. Big Tobacco used censorship for many years (probably still do), because they have things to hide. We have nothing to hide. There are more topics on here about drugs than there ever would be if we didn't attempt to censor it; this topic, for example, is clearly about drugs and would never exist on this forum if we stopped being such babies about it. It is one thing to remove a thread called "How can I put X and Y in my juice", because that directly promotes illegal activity. Complaining about funny names or old timers' swapping college stories, however, is silly and counterproductive.
