Man at 5 years already? To be bullied at that age is terrible and kids must have been indoctrinated by parents for sure, my son is 4 and in his school there is a black kid, a Chinese one and twins mixed like you but there is no bullying there
I was told by a few of my teachers that, I would never amount to anything, that I was and shall always be nothing.
That widen my eyes, really??? That's to be told to the principal and get the teacher punished, you can't tell that to a kid
Your story seems from the 1800'
I agree school just promotes parroting and conformity... I learned that too, but I had to get through it with a good vote, so on appearance I just used to please teachers, like in texts written I would write politics that the teacher liked, but inside I had my own ideas
