Well, I dunno about calling the KKK and Nazis evil. It seems too much like a media-arranged manipulation, repeated enough times so everyone ends up believing it. It reminds me of those Warner Brothers cartoons with signs nailed to the trees saying "TURN BACK!" "Bad stuff is here" "Go back" "This means you". So most people are lost in the forest and never find out exactly what is being talked about.
Initial coverage of Waco and Ruby Ridge said that dangerous fringe groups "bent on violence" live there, but it turned out to be the FBI line parrotted by the media. REAL violence was committed against them, they were victims. Questions were raised as to whether the FBI set off explosives at Waco themselves to kill off David Koresh's group. At Ruby Ridge, the FBI shot a mother holding a baby IN THE BACK, killing her.
But thanks to the Internet, you can find out for yourself about any group, straight from the horse's mouth, and if you think there is anything evil or destructive about them, objective proof should be obtained. Are White supremacists evil? Go to the White supremacist website like http://www.stormfront.org and find out. Are anti-Semites evil and destructive and irrational in thinking anything ill about Jews?
