Sam2,
I’m just saying that if you want to convince anyone of anything you have to begin by agreeing on the same premises.
If that’s true, then there’s no point in discussing it. They don’t agree to the premise that there’s a RS”O who want us to do a bris to begin with.
Rather, we argue from the point of view that they are infringing upon our beliefs, and those who practice MBP indeed believe that it’s an age old practice.
He has a right to his opinions, even if he’s in the minority.
So do all of the big talmidei chachamim who feel that he is a rasha. The negativity you are seeing here is not merely from cynical, anonymous bloggers. There’s no reason for you, who are broad minded, not to accept the legitimate opinion that he is not a talmid chochom as a valid opinion.
