You and I both grew up in open minded homes, by which I mean to say that we were exposed to secular culture somewhat. So when some random dude would ask us if we want to study for a test with him, we would know how to politely refuse. Whereas a sheltered BY girl that has never spoken to a male other than her immediate family members would find themselves unable to turn the guy down (guys can be persuasive of need be…)
Most BY girls would’ve avoided having any discussion with a male in the first place but they would definitely avoid studying with him one-on-one. Unless a large part of the reason they went there in the first place was to get male friends and they were dishonest about their motives.
The same would occur if someone would ask a BY girl a question on Judaism. Firstly, she most probably wouldn’t know what to answer, as BYs generally don’t give kiruv classes to their students, and second, she would end up getting into a conversation, and possibly an eventual relationship, with whoever asked her the question.
That’s a problem with BY education, not with college. Why would someone spend thousands of dollars on their daughters for 12 years to get a Torah education if that education doesn’t teach them the basic tenets of Judaism. You’d think that at some point in 12 years they would have taught “mah shetashiv le’apikores”. If a secular kid knows more about hashkafa than they do after having spend 12 years learning about Judaic hashkafa, that’s not exactly a compliment about the way BY education is set up.
And she’s going to end up in a relationship because they had a conversation? If she was really all that frum she would’ve avoided the conversation to begin with. If she was really all that truthseeking she would’ve called a rabbi to find out the truth.
