Do you think a mohel should ask parents if theyd like MBP done?
So we are discussing the mohel’s personal ethical responsibility then.
Depends. If the mohel holds it is required min hadin, he should obviously not ask. If the mohel holds it is not required, then maybe he should.
Mostly, the parents should just ask him when they hire him. Unless they are idiots. And if they are idiots, then I don’t care anyway.
