Something that should have been said long ago:
"Every fake attempt to understand "why" Columbine happened has always turned into an act of willful self-deception. At first their parents were blamed. But then we learned that both grew up in two-parent homes, and both openly loved their parents, even apologizing to them in video diaries. As Harris noted, quoting Shakespeare's The Tempest, "Good wombs hath borne bad sons." Then the Internet was blamed, Doom was blamed, violent movies, the NRA, lack of religion:everything was blamed except the most obvious cause of the attack: Columbine High School.
And what a horrible place it was - and is. After the massacre, numerous parent, students, and ex-students went public about the school's "toxic" culture of brutality. Students were routinely beaten, assaulted and humiliated right in front of the teachers and administration, whose jock-principal not only tolerated it but loved the bullies. As one jock from the Columbine High football team bragged after the massacre, "Sure we teased them:If you want to get rid of someone, usually you tease 'em. So the whole school would call them homos."" - Mark Ames, Exile.ru
