So What ?

When the teens who agreed that violence was acceptable were asked more specifically about rationale for such behavior, most noted self-defense (87 percent) and to help a friend (73 percent). However, more than a third said violence was acceptable to settle an argument (35 percent) and for revenge (34 percent). Other justifications were dislike of the person who is the target of the violence (22 percent), to gain respect (21 percent), peer pressure (14 percent), and simply for "the thrill" of it (10 percent).

What's all the hand wringing about? Sounds like what the results would be where I was of that age. I must admit to being a bit disappointed about the 87% considering self-defense as the reason violence is acceptable. Seems to me it should be more like 100%. I have no respect for those that find violent self-defense as being not acceptable.
