For all those people talking about “college professors filling your head with schmutz”, have you been to a college in the last, I dunno, 50 years? Sure, if you’re doing the standard post-high school thing, sleeping on campus, and taking all recommended Freshman course work, you’re going to hit some of the worst aspects of secular society. But that’s all optional! Pick any career that a frum person can go into, and there’s guaranteed to be a track that lets you take only the required courses and have nothing to do with college social life.
The main reasons for a frum college these days (which we already have in Touro and Skokie) is seperate classes and working around Yomim Tovim. I’m not sure what a Chareidi college will accomplish that we don’t already have (other than some idiots trying to burn it down, as what happened when Touro tried to open in Monsey in 1995).
