Hell YES!!! Children are not sex objects or adults fetishized dolls to dress up and play with. Teachers should not be allowed to teach ANYTHING sexual or political or religious in nature. Full stop, until they are in HS, they should be taught the basics and the rest is for their family to teach them. In HS you should be taught Home Economics and how to be responsible enough to MAKE any decisions for yourself while still under your parents control for consent. At 18, you’re off to find out all the rest. Stop sexualizing children who have no sense of that until they have context to form opinions. It’s disgusting and unacceptable.
