Menachem, good questions. I think a school should have separate classes for those who are preparing for college and those who will go into learning/teaching. Making them sit in a common “math” class is torturing both. This can be partially augmented with online assignments. I would have no problem if school teachers halochos of beards, mentioning what the approaches are. I realize it would be tedious to be inclusive without getting ridiculous, but it is possible. I heard for example a Sephardi chacham routinely say Ashkenazim do this, we do that… Beit Hillel used to do this and even shulchan aruch is written this way … Really if you focus on classical Jewish texts, you can teach them without being divisive most of the time.
