If prominently identifiable YU institutions such as Einstein and Cordozo do terrible chillul Hashem, then it is entirely appropriate, if not required, to respond to such activities with criticism of “YU”.
I read the transcript from the YC gay event shortly after it occurred. It was not excusable, including what transpired verbatim. I’m almost sure I recall an openly “proud” student speaker at the event justified toeiva in veiled — yet easily understood — language. And the existence of the event itself — an open forum of that nature — gave legitimization to toeiva. In fact, even RIETS R”Y Rav Twersky very strongly criticized it in unbridled and unambiguous terms.
