I'm new here and not wanting to ruffle feathers, but I read this thread and wanted to make a few comments, just my 2 cents 
As a person with allergies (though not e-cig related) I know how hard it is to both find products you can use and how difficult it can be to get those answers you need in order to make informed decisions for yourself.
I have noticed in e-cig forums that there is a general tendency to run into walls on this issue. I don't think the wall is always purposefully put there, but I notice it anyway. If someone is facing the possibility of anaphalaxis when using certain products (peanuts, berries, etc.), then that is a valid question.This is a real concern for some people. I have to have epipens with me at all times to prevent reactions long enough to get to the hospital for medical attention for certain triggers. So, someone asking for disclosure of certain/specific ingredients, not proprietary formulas, is not unreasonable. But, it is also common to find the same types of walls with food in restaurants, so I know this is across the board and not just specific to e-cig vendors.
If you have concerns over the safety of vaping, that is also a valid concern. I am of the mindset that I vape because it's safer than smoking, not because I find it to be the most wholesome habit to take up. But, that's my decision for myself. Arming yourself with knowledge is the best thing anyone can do. So, read, read, read, then read some more to validate what you previously read. For some, they want to vape the safest way they can, and there's nothing wrong with that (kudos to them!).
If you encounter defensiveness when asking vendors legitimate questions, then my suggestion is move on to another one.
If you encounter it in the forums, then you just accept human nature for what it is, flawed and tempered by emotions. Someone said this earlier also, that the written word can be misconstrued, misunderstood quite easily. Maybe they were defensive, maybe they weren't. But, don't let that stop you from getting the answers you want and deserve as a consumer.
