I can make such judgments because I have personal experience with BF. Some of the claims by habituators are hard to believe, even for proponents. Those claims include English speaking BF, BF being impossible to photograph, winking in and out of existence, and the ability remotely to disable electronic devices. All stuff you likely think are bunk. Well so do I, because I have experienced none of it even though I have a limited history of BF encounters. Some of these might be possible, like speaking English, but the other claims I have not experienced. Until I do, I am as skeptical as you are. As a I often mention, I came into BF research very skeptical about the whole thing. Only when something rings true based on my own experience, do I give it much credence. But I do not dismiss everything out of hand. That is not science but a dogmatic belief system, which skeptics and proponents both can be guilty of doing.
