You don't think there are any conservatives studying law, science, medicine, economics, or business? You're either making a joke, or are ignorant.
Or, maybe the orgies, free sex and godlessness taught in college don’t allow any conservatives to survive till graduation.
I went to some pretty liberal schools, and orgies, free sex and godlessness were never part of what we were taught in class. Certainly, some students choose to participate in such activities outside of class time, but that's their choice- they are legal adults, after all. Colleges aren't babysitters and it is not their job to make sure that students live their lives in a certain way.
That's what you learned in college. That western civilization can survive depravity. It can't.
