The question this video addresses came up in another thread.
I was asked to name any “gender-bending” books I consider it appropriate for parents to remove from schools. The video names two, “Lawn Boy” and “Gender Queer” which happen to feature explicit sexual content. The mother who objects to them quotes both books, making this video NSFW.
My theory of effective education is based on the traditional curriculum, sometimes called the Trivium (see Wikipedia). Strictly speaking, sex education has no place in the traditional model, because it is irrelevant to the subject matter.
I do believe children need to learn about sex so as to avoid mistakes and misconceptions that can have life-altering consequences, but I disapprove of the two books in the video because they violate Trivium principles. They do so by promoting social values instead of teaching the mechanics of rational thinking.
