Feif un:
I agree with you in that Yeshivos shuold not be teaching twain during secular studies and teaching against it in Jewish studies. But maybe the school is required to do this by law. In which case the yeshiva should be making it very clear to the kids that although it there are problems in reading these books, you would not be able to have a yeshivha education if we took them out of the curriculum and so we have to take the lesser of two evils. Other than that of course I agree with you that yeshivos should not be setting a confusing example.
HaLeivi:
Your second statement is what I was actually aiming at. A child who is not presented with 2 opposing views will be confident when he experiences situations where someone is acting wrong. I am not saying that in some of the cases the rebbeim were wrong, but perhaps if as a child he was more confident in what was wrong and what was right, he would have felt more confident as a child in dismissing the rebbeim instead of Judaism.
