Von Brunn was a white supremacist , neo-Nazi and Holocaust denier who had written numerous antisemitic essays , created an antisemitic website called '' The Holy Western Empire '' , and is the author of a 1999 self-published book , '' Kill the Best Gentiles '' , which praises Adolf Hitler and denies the Holocaust including propagating the belief of a supposed white genocide . After the shooting , traces of his personal writings and works online were deleted from many websites , including AskArt.com , FreeRepublic and his personal user page on Wikipedia where he was indefinitely blocked , the latter said to constitute " a violation of policy of hate speech " . He also made posts expressing his opposition to the Iraq War , and felt that the September 11 attacks were an " inside job "
