"While I understand the dire need to "reign in" todays teenagers and instill clear and uncompromising standards of Tznius, not only with regard to the exact number of inches or centimeters that are permitted but also in regard to the sense and feel of Kol kevuda bas melech, nevertheless, presenting mussar as halachah and chumras as psakim is not the way to do it. That was the mistake of the first woman in history, Chava, when, after touching the aitz hadas, said to herself "I crossed the line already - i touched it and didnt die, so I may as well eat it." The Kli Yakar explains, that Adam added a "siyag" and told Chava that she is not allowed to touch the tee. But Chava did not understand that touchign was just a siyag, and she thought that when she touched, she already "crossed the line" of doing the aveirah, and she didnt die, so she may as well eat."
Bonus points if you can tell me who's he's criticizing.
