Read the excerpt from warriors don't cry. the next day, in the sunday paper, i saw a pitiful closeup photograph of elizabeth, walking alone in front of central on that first day of integration. it pained my insides to see, once again, the twisted, scowling white faces with open mouths jeering, clustered about my friend's head like bouquets of grotesque flowers. it was an ad paid for by a white man from a small town in arkansas. "if you live in arkansas," the ad read, "study this picture and know shame. when hate is unleashed and bigotry finds a voice, god us all." i felt a kind of joy and hope in the thought that one white man was willing to use his own money to call attention to the injustice we were facing. maybe the picture would others realize that what they were doing was hurting everybody. what is the central idea of the excerpt?
