I wouldn’t say a lot of what you think I would say.
But to play along, …… To which I would say the Beis Yoseif himself was aware of three different struggles for legitimacy among the leaders of the Jewish Communities of his day.
Even if I would concede to your version of history, it would still not help with when the gedolim split their opinions. Like AH”U or the fallout of Shabbsai Tzvi. And you would have to leave the Ramchal out, because nobody supported him in his lifetime.
In our day, a lot of the struggle isn’t about authenticity. It’s about balance.
