Dr. Suess, do you have a source for that?
If you were to look in the back of Kovetz Ha’aros you will find a tshuvah given by Rav Elchonon saying that secular college — let alone YU– is permissible assuming you don’t fraternize with ovrei avairuh, you dont learn/ study and kfiera, and a third requirement which I don’t recall.
I think you may want to verify any statement you make before ascribing it to someone, because then you portray that person (in this case Rav Elchonon Wasserman) as espousing a belief which he did not.
