Cardinals and Crossing Lines

R. Yitzchok Adlerstein's post today about Chovevei Torah hosting Cardinals in its beis midrash seems to be generating some controversy. Let me direct readers to my posts about this issue when it happened, under different circumstances, at Yeshiva University.

Cardinal in the Beis Midrash I, II
Interfaith Dialogue III (less relevant: I, II, IV, V, VI)

As to the incident at Chovevei Torah, I just don't know enough about what went on, or the goal of the event, to have any sort of intelligent opinion on the subject.
