With hot takes like this, I don't know how we could possibly think only socializing children in the insular settings of thier homes is, or would be a good thing!

Schools are, and have always been about teaching more than the basics.. in fact, it's safe to say it's virtually impossible to remove social development from schools. Also you say we should be teaching them how to survive as adults.. ok, they are going to come across transgender and other LGBTQA folks in thier lives, some of them may infact be trans themselves, wouldn't a means of survival, especially for the later catagory, be a healthy and rational understanding of others and their own identities?
