rd and others:
As others have wrote before a chosid shothe is one who sees a woman drowning and does not help her. A case of real pikuach nefesh, not as this case here where there was apparently no danger, she could get up by herself (maybe with a DROP more effort, it’s her fault, why would the young woman in question pack more than her weight?)
And no, we don’t rationalize with HaShem’s mitzvhos. He says not to touch, we don’t; not this way not that way. ?? ??? ??????, when we keep HaShem’s commandments to the tee, others will admire us, not mock us.
And besides we don’t give a hoot to what others care or think about us, while carrying out HaShem’s will. ?? ?? ???? ?????. Furthermore we should be too preoccupied to even notice.
