I should say, as I've generally said before, that (1) I don't think homosexuality is morally wrong, (2) I would want to teach my children to be tolerant of homosexuality, (3) schools inevitable teach some non-universally-accepted moral values, (4) schools should teach children to be tolerant of homosexuality at least to the extent that students don't beat up or taunt others based on their homosexuality or perceived homosexuality, and (5) there's a perfectly plausible argument for schools teaching children tolerance of homosexuality more broadly.... But such teaching should at least comply with the Constitution, avoid falsehoods, and avoid fallacies. Good motives don't justify bad teaching.
