No one bashes Gedolim. People bash the idea that there is a concept of “Gedolim” as interpreted by the current “Yeshivish”/”Chariedi”/”Ultra-Orthodox” world.
I don’t know what you mean by that. When I say that, I mean that my rav knows his place, and knows that he shouldn’t be arguing with the people that all the other rabbonim are asking shailos to. It is just about knowing your place.
There has never been an idea in Judaism that each person who happened to get smicha in basar bchalav is on equal terms.
