Sam2,
For the record, I wasn’t saying that he’s a rasha, but it wouldn’t surprise me if there are gedolim who hold he is. He certainly seems to be very antagonistic towards the RW, especially chassidim.
I can relate a (unconfirmed) quote about him from a well known litvishe RY – “He’s a second rate talmid chochom… and a third rate scientist”.
This was before the MBP controversy.
And yes, my point wasn’t to prove the ancient origins of metzitza b’peh; my main point , you conceded.
It is mistaver, though, that it was performed b’peh in the times of Chaza”l and earlier. The issue is whether b’peh was b’davka, or simply the available method.
