Syag,
Joseph can openly comment about what is taught in colleges only if he went there himself? Otherwise he is one “Who sits in a dungeon and describes a rain forest? Who sits in a desert and describes what rainstorms look like?”
That would exclude most of the comments from some of your favorite commenters who are clearly less informed about what they comment than Joseph is in these matters.
What is taught on campuses these days is readily available information. The schools themselves write about it.
Any sane person knows that Joseph’s comments are not what put your children at risk. Willfully and gleefully ignoring deios kozvos that are antithetical to the Torah and having them taught to your children is what puts them at risk. Colleges are certainly not known for their moral outlook and for moral activities being practiced there.
