No, the "problem" is that you expect a vendor to be a great trader. Most are not. Most can't trade their way out of a paper bag. But none of that is particularly relevant. What matters most is whether or not what the vendor has to say has value, and you can determine that through your own back-testing efforts, if you know how to do that. If you don't, then it's up to you to learn how. If you have no interest in learning how, then you're pretty much screwed.
In any case, my comments on fear stem from my experience as a psychologist (I obtained my doctorate forty years ago). If you believe that they don't apply to trading, that is your privilege.
