2) MBP doesn’t have to be performed by the mohel, it can be someone else.
Why? After all, if it is part of the Mitzva then it needs to be done by a Bar Hachei?
The gedolim who say not to do it are the ones who hold it isn’t halacha anyway.
Yup. And those who hold it is M’akev will not care what to government says, which is why we end up where we are. Two groups of Torah Yidden not understanding each other, and accusing each other of being betraying their religion and being unreasonable.
My point here was that MBP is (logically) more of a sakana than eating an onion that was left out overnight.
