“You have proponents of both positions here.
Whose “common sense” are you going to use as the arbiter for all of jewery to go by?
Do you really not see how untenable a position that is?”
Just the opposite. Your example proves it is teneble. Judaism is still going strong your Rav says better to make a fuss mine follow s halacha (I couldn’t help myself) there’s nothing untenable about that.
if you find a more horah who says being meanes is not such a big deal. Definitely better than lying OK, he’s strange but the world doesn’t fall apart. Nothing untenable about that
And out of curiosity, what’s worse sitting next to an erva or being meanes a penuyah who isn’t a nidah
