No one is coming to stop this. Your only option is to let your own school know you will not allow your child to take part

Part of the email sent to the principal:

“Personally I do not know of any parent who would willingly encourage their child to enter a lifestyle that even potentially leads to disease low self-esteem and diminished self-worth. The best parents I know encourage their children to rise early go to bed on time have healthy non-sexual friendships disregard excess worries about sexuality during adolescence and redirect the focus towards academics, sports, healthy hobbies, life goals and self-discipline. The LGBTQ agenda, on the other hand, encourages young people to dwell on themselves, especially their budding sexuality, and experiment with life-altering and dangerous activity. Because their agenda is dangerous, I respectfully request that I be informed when the LGBTQ message is promoted at school“
