Gadolhadorah,
The prescriptive “should” applies equally to adhering the advice of my rav when opining on matters of halacha and adhering to the advice of a respected physician on matters of medical care etc….
Fine – so why didn’t you write it that way from the get go?
the point is obvious.
Those darn Jews who don’t get the point.
I don’t ask my doctor to paskan on arba minim nor do I ask my rav to paskin on my EKG.
Straw man. Nobody’s going to his or her rav to get an EKG evaluated (unless the rav happens to be a cardiologist). Jews do go to the rav for shailos surrounding a diagnosis. And maybe a bracha for health or a refua.
