Boys need fathers as role models, a stable family home, and male friends to learn about friendship, healthy competition and personal responsibility.
For boys, girls are generally icky until they reach somewhere around age 13. Effeminate boys also provide lessons, although not the ones our presently sick culture imagines.
In reality, there are virtually no "non-binary" children.
That baseless assertion is a fabrication of a sick and twisted cultural elite which seeks to destroy the family as the central organizing unit of society, and replace it with the State.
All of the above was once considered common sense. Now, it would get me shunned or banned on Facebook. Which is one of many reasons I have no presence there.
