I think this is a verifiable problem. People blather out all kinds of stuff, and a viewer says these people are nuts, and decide to stear clear of a particular hobby. It must all seem overwhelming. There are lots of threads like this all over the internet. Oftentimes though an answer to a particular question is complicated, and a poster just isn't prepared for that. "What's wrong with my car, just tell me, what could it be given these symptoms?". Well here's a list. Question is what are they going to do about it? Oftentimes people, and I must say myself included, are just looking for a simple answer. But them all the "experts" (and some are, but not me) put in their 2 cents. And the questioner walks (or runs) away.
