We are so afraid of differences that we use many tools to mandate conformity or get rid of the problem. Peer pressure itself accomplishes this. Some who are different from the “norm” stubbornly persist, resist, and thrive. Most do not. The pressure to be accepted is too great. My sons had teachers in elementary school who allowed kids who needed to, to roam the classroom and explore a rich assortment of fascinating materials. Making them sit in a chair quietly and do their lessons simply would not work. I don’t know how they have done, but at least at that point in their lives they were accepted as individuals and classmates.
