Furthermore, no one nowadays can make up such a shitta without backing it up with rayas.
You keep saying things that were never disputed and making it seem like what I’m saying is dependent upon them. I said to go ask them. Exactly how could you possibly understand that, or anything else I said, to mean that the baalei Mesora can simply invent things out of thin air?? And the extent of the raya need be only the dictates of their Mesorah itself. And you cannot claim from ignorance about Mesoras to “prove they get that sort of authority”. Go learn about Mesoras first.
