youdontsay: Why is that unfortunate? Would you rather live in a world where we can chose a “forgotten gaon of his time” over the Mishnah Berurah? No matter, you guys have shown that the shittah exists, so I’m not saying you’re wrong. I’m still not convinced that it’s mainstream perse to hold the MB didn’t have all the information and made mistakes, and in your last comment you seem to also suggest that it is “unfortunately” not mainstream.
I’m not going any further with the baal gaavah argument. Clearly nobody in the real world holds that holding by Rabbeinu Tam’s tzeis or 16 amos reshus harabim is gaavah with the exception of a few CR posters.
