"What if they used Superman to teach children the values of tolerance and fair play and the importance of accepting other kids regardless of race, religion, or national origin? What if Superman could teach a generation of children to reject those who preached prejudice and hate? After all, the entire country had banded together to win the war. Now most everyone was banding together to build a peaceful and prosperous future. Those grim photographs and films of mass graves and starving concentration camp prisoners had made an indelible mark on the public mind. Could Superman lead the way?"
