Leave kids alone... hmmm... sounds pretty trite. This notion really needs to be unpacked.
As I said earlier in the thread, my sister was an inclusive teacher for many years. She wasn't indoctrinating any of the students to become gay, trans, bi, or teaching them how to use a litter box, nor forcing them to read Das Kapital. Rather, as per provincial government guidelines, she fostered a safe, inclusive, educational environment where kids were free to express their sexual and gender identities without fear of reprisal or bullying.
This did nothing to "steal their childhood". But what it did do is allow them to be themselves in class, allowing them to be free from the bigotry of the outside world. So, rather than destroying their innocence, she helped to protect it by creating an environment where they could be authentic, be themselves. And she was not alone in this... teachers across Canada and around the world share this goal.
