You’d best get your child out of that school because there is no arguing with these people. Let’s say the speaker is not just an example but for real. They are into this stuff because it makes them feel superior, ore woke, better, higher-class etc. Just call them on it.
As in,’what makes you better than me to be lecturing me like that? Who gave you a license to set yourself up as perfect? You’re not higher-class or superior to me...etc. Address the real situation, not the phony ‘anti-racism’ cover that these people present, they’re really saying “I am better than you and I can order you around’. Address that.
Then, get your child away from people who push propaganda as ‘novels’ or ‘stories for children’ etc. because you will find your child is forever turned off of reading. They will not read, they will escape to video games or anything that gets them away from books that tell them they’re bad. It will destroy their love of literature forever. You don’t want that.
Thanks for the tip. I don’t have children in public school. But a feel for the student whose parent complained.
