There's no cure all solution. I consider homeschooled children taught to live their lives by regressive religious texts to be just as broken as the cult of Tate.
If any intervention will still yield roughly equivalent mixed results, I always err on the side of more access to information. A child can gravitate to Andrew Tate's toxicity, or they can look up facts about the confederacy their parents told them fought for "states rights and freedumb!"
In a perfect world, loving parents should be available to provide opinions and context, but I'd rather that child have the opportunity to seek out a rational, benevolent path if the parents attempt to indoctrinate them to their worldview with no other options.
The parents most interested in dominating all information their child receives tend to be the same ones that get mad at the schools for teaching children that genitals exist, the universe is billions of years old, and their country wasn't always perfect, stuff they need to know for life whether their parents like it or not.
