>>>The better question is why didn’t YU shut down all their clubs at their graduate schools over the last 25 years
They would have to close their graduate schools down altogether to do so. Their graduate schools are secular schools that accommodate frum students. There probably isn’t even any legal option to classify a graduate school that primarily teaches secular subjects and only gives secular degrees as a religious school. The Touro graduate schools also have toeva clubs. I even found explicit reference to them on Touro’s own website. No one says a word about that either.
