Bitcoin is from people, for people, that's right. But it's normal that some people have their doubts. In my personal life there are non Bitcoiners that do like the concept, but are afraid of the fact that no one is in control of Bitcoin. They don't understand how it has value since no one is in charge, etc. I think it's better from them to express their concerns so we can inform them about how Bitcoin works, instead of these people spreading false information due to their ignorance.
