HaKatan: I don’t even know where to begin with this. You are taking an article by one Overes Aveirah as an indictment on a whole community. I would hope that someone who knows what Jews have gone through throughout our history would be able to see past that.
Rav Schachter talks about when the cardinals visit and why and why YU lets them in the Beis Midrash. Before they come, someone always announces in the Beis Medrash that they should be ignored and that learning should continue as normal.
I cannot answer why Broadway shows are Muttar. I know people have been given Heterim (I also know of several people who bring iPods to listen on during Kol Isha parts), but I do not know why they would be Muttar.
You seem to have a very strong complaint against a group of people and are not giving a real support for your indictment of a large group of Frum Jews, unless you think that Broadway shows are enough to Passul an entire group.
