"Bullying was so deeply ingrained that, as the American Psychology Association Monitor wrote, "Columbine students said teachers and staff did not seem to notice the bullying and aggression; apparently such behaviors were culturally normative." Here again is a perfect, modern example of how what is considered normal is not only tolerated, but is simply not seen, no matter how brutal it is. From this example, it's a little easier to understand how whites accepted- did not even notice- slavery, in spite of its cruelty. Many parents and students said that the reason for Columbine's bully-coddling culture went straight to the top, to principal Frank DeAngelis, himself a jock."
