DY: I’m not aware of all the details. Can you actually show where a major Gadol has called him a Rasha and not just a Da’as Yachid?
You also make a very good point. I’ll retract my previous arguments about what we can prove and stuff. Not that I think they were necessarily incorrect (for all we know MBP actually did start in the time of the late RIshonim), but because they’re irrelevant.
