Can a school make parents lose custody of children?

Public school is less learning and more systematic child abuse. I remember as a kid getting picked on a lot. Part of it was my family had lower income than the city we lived in so I was "That one poor kid". I also remember despite a lot of kids not having lunch or lunch money, no one really noticed it. I remember everytime I complained of bullying they said I was lying and they kept threatening take me from my parents. At one time I visited a Facility my mom later told me was a group home. That I would never get to see her again. My mom seemed disinterested talking to the lady like she was just listening to a sale. Than in the car said I not going there. She told me if they didn't visit she would get in trouble with the school. So she visited and we left. She was told she had to go here or the school would have her arrested and me locked away forever. Everytime my parents complained I was being bullied the school threatened to have my parents arrested for bad parenting or have me locked away for being a liar and fighting with other students. Even when I complained several times myself that I was being picked on and they stated that was impossible and kids would never get in fight at school. I am curious though now can a school legally steal your child like that?
