In my four years of year-round undergrad school, the only course in which the existence or nonexistence of God was discussed was "Early Modern Philosphers," where we examined the proofs of Descartes and others.
I know some of my fellow students were devout Christians, but no one seemed disturbed by leaving God in Heaven during classroom instruction. None of my professors or instructors ever attempted to promote an atheistic stance during those years.
The notion that colleges militate against religion is just flat-out silly. Most profs already struggle--largely due to unprepared students--to cover their subject matter without introducing extraneous material.
Perhaps more high school grads would be prepared if their school boards spent less time worrying about religion and sex.
