Nuremberg has taught us that it is our moral obligation to meet the messengers of hate with opposition and they were met, of course, with that. The political right must expect moral outrage to their incendiary message. The extremist right is gun loving, gun toting violent happily screaming they were going to kill their opposition if they had to. One need only remember the murder of 168 innocents 19 of whom were children by the right wing nationalist, Timothy McVeigh, when he parked a truck packed with explosives near the Murrah Federal Building in Oklahoma he thought a dandy way to lodge his protest against the federal government. More than 650 other people were injured in the bombing that damaged or destroyed more than 300 buildings as well.
Given the past horrors of extremist right wing nationalist movements as being those who kill those they deem the "other" by the millions because of an ethnic supremacist irrational rationale it is incumbent upon all moral men and women of good conscience to oppose them by any means necessary!
