Joseph –
“Once you start counting newly discovered Psaks, give it now time and you might discover even more psakim that change the majority back the other way. As stated, we don’t change what it considered the majority based on newly discovered psakim. ”
As I have stated to you more than once, it would help if you learn the basics before you comment. That means simply opening a Shulchan Aruch and learning mechaber, Tur, Magen Abraham and T”Z. See that they clearly say, that the accepted psak is that the MAJORITY of the poskim uphold that אין לנו רשות הרבים בזה”ז”
That was until the Mishkenos Yaakov compiled a list of other “new” rishonim that say differently. So your above statement indeed holds true regarding the above psak.
As you can see the Bais Efrayim response was that a) the minhag is based on the חכמי צרפת ואשכנז b) that in reality there is indeed a majority as the M”A and T”Z.
The same applies to the MB, that the minhag is supported my the majority, and not the other way around.
Meaning, we are to go by what the M”A, T”Z and Mahrit tzahlon have ruled as the majority.
All he is basically doing is proving them correct.
