People arent idiots if they dont know the ins and outs of technical halacha that comes up a few times in a person’s life.
(How many people know that theres a machlokes regarding performing priah as part of the chituch? obviously this is but one example)
And besides I guess I do care about all people even idiots
What if the mohel holds it is required but he knows that the parents would not hold that eg they are not chasidish (and yes many many non-chasidim hire chasidish mohels)Do you think he should ask or just go ahead and do it?
