Conservatives and christofascists freak out so much about queer & trans kids having basic human rights because they know that if we really protected kids in this society (here I speak broadly of North America), it means giving children a good education, access to medical and social ressources, and protecting children’s autonomy and dignity. Longterm, this helps shield those children from fundamentalist religious indoctrination and protect them from gendered and sexual abuse. This is a direct threat to many international and very wealthy Christian religious communities.
Anyways, if you ever see the words "parental rights" next to "religious freedom" all of your alarm bells should be going off at top volume.
