A third point.
Most of the observant scholars who grew up in yeshiva (or it’s equivalent) and ended up in academia, did not write for the masses. Especially the masses in a yeshiva. The only ones your system “proves” is against Graetz and Weiss. Those two wrote for the masses. And the masses ate it up in their day. Even more than that ridiculous blog in our day that you think I read.
Point being, the idea that yeshiva guys don’t look at Albek or Sholem doesn’t prove anything. On these topics they don’t look at Hirschler or Margolis either.
