I don’t think talking about a thing that goes against any individual religion should be considered protecting religion. If my religion teaches vegetarianism, can I opt out of any books where a character eats meat or hunts? Can I be exempt from learning about early humans or the food chain because it involves learning about their diet? The answer is now yes, and I think it does a huge disservice to children. Reading a book about a gay couple is not forcing you to be gay or even support homosexual relationships. It’s just showing you that gay people exist and that’s legal and some gay people have families and are happy. You can think it’s morally wrong, but it’s happening and it’s the schools job to educate children on things that are happening. I know people who were removed when evolution was discussed. They’re no longer religious, but they have this gap in understanding they now have to fill in because their parents didn’t want them to know the science. I think that’s terrible and does not help, but I support that more than the book thing because at least you can argue testing a child about evolution forces them to say things they don’t believe in whereas just reading or hearing about gay people doesn’t make you do anything.
