When you try to remove lgbtqia+ content from your child’s curriculum, they will simply seek it out on the internet. And they will know you attempted to shield this content from them. As a result, they will feel shame and guilt for accessing it. If your child happens to be one of the ~10% of people who do not identify as heterosexual, they will associate shame and guilt with their identity, leading to psychological distress. According to The Trevor Project, “LGBTQ youth [are] four times more likely to seriously consider suicide, to make a plan for suicide, and to attempt suicide versus their peers.”
Your educators know how to handle and navigate difficult topics with your children. They have at least a 4 year degree in exactly this. They also work with a support staff including counselors, psychologists, and deans. I trust educators to curate content and teach our children about race, sexuality, and religion a heck of a lot more than “concerned parents.” You should too. If for some reason you don’t, you might want to consider home schooling.
