Is it also wrong, in your view, for a school to teach toleration and understanding for people of other races, religions and nationalities? GLBT people are a fact of life, and learning about life and the world is what education is supposed to be all about. If parents want to ensure that their particular prejudices and/or religion-based feelings about certain groups of people are assimilated by their own children, they are pretty much free to do so, as long as such indoctrination doesn't become abusive.
