shein: The letter is also printed in the sefer from R’ Romi Cohen, which has glowing haskamos from many Rabbonim.
nishtdayngesheft: I know all about R’ Cohen. He was the mohel at my son’s bris. My point was in response to shlishi, to prove that metzitzah is for medical benefit. These are not my words, they’re the words of the Chassam Sofer.
The Chassam Sofer also wrote, “However, we have no dealing with hidden matters if there is at all even the slightest concern of a health hazard.”
In this case, many Rabbonim hold there is more than even a slight concern. They, however, realize that there are others who disagree.
R’ Tendler goes a step further. He holds it is full-on pikuach nefesh to do it, and that is why he came out so strongly against it. Not out of disrespect, but out of concern. He feels that he is literally saving lives.
