But why limit public shaming to just skirts you have an issue?
We can issue an entire bulletin with the names of everyone who is seen doing anything that is in any way inappropriate.
We can have a list of names of everyone who wears skirts above the knee, everyone who has a television in the house, everyone who talks in shul, everyone who acts like a baal gaiva, everyone who has internet in the house, everyone who has a non-kosher cell phone, everyone who does not buy chalav yisroel… and everyone who embarrasses someone else berabim.
This will be for their own good.
And when everyone sees their name has already been submitted by someone to the paper, they will actually start working on their own middos. And Klal Yisroel will reach new heights.
