Pashuteh –
The glass house bit, you are alluding to, is a non-Jewish concept. You are trying to deduce that it is improper for ANYONE to correct anyone else, “since no one is perfect.” In Torah Judaism, a Yid is OBLIGATED to give tochacha. You, like so many other mitzvos, would like that repealed and reformed.
If Judaism ever finished reforming itself to your specifications, there would be nothing left of it. In fact, the “Reform” and “Conservative” movements are just that.
Yes, yes, I know, how dare you be corrected. How “kanaish.”
