LB, you will find people in all circles (even Litvish ones, and maybe even in some MO ones) who will take on high authority. But you have to be careful and use your seichel. Not everyone who takes on high authority should be.
One should be wary of anyone who claims that they can tell you for certain what you should be doing if you didn’t even ask them and they are not a well-known Gadol Hador (unless we are talking about a straightforward halachic issue). I’m saying this from experience, as well as a sense I’ve picked up from your posts that you may be too trusting (not that you have to assume that I know for certain what you should be doing either :)).
