More than the actual subject matter, the real danger is the culture shock. After being taught for eighteen years that modern secular culture is venal, shallow and a pointless pursuit of pleasure, our BY meideleh (or our BM bachur) gets to college and sees that it ain’t necessarily so. She observes that seculars can and mostly do, have happy, focused, fulfilling lives, and that college involves real intellect and scholarship. This often engenders doubt and causes her to begin to question what she was taught. Can you say, “slippery slope”?
It has always seemed to me that it is counterproductive and dangerous to teach such derogatory things about the secular culture when anyone with half a brain and two eyes can see that it isn’t true. A better course would be to inoculate our kids against doubt by focusing, not on the superiority of our culture but on the singularity of our mission which is to be mekadesh shem Shamayim and Standard for the Nations.
P.S. In the interests of full disclosure, I went to Engineering School where we only dealt with the minimum required Humanities.
P.P.S. College or otherwise, I feel it is important to learn as much as one can about as many things as one can. There have been many times in my 43 year professional career when some random bit of unrelated information has proved relevant to a problem at hand.
