It's pretty simple - Anglophone North America is a left-wing polity and always has been, its deviant and extinct Confederate branch aside. You won't find a single leftist trope that isn't repeated over and over again in the 17th, 18th, 19th and 20th centuries. As Earl Browder put it, "Communism is 20th-century Americanism."
This is why we're all supposed to be all nuanced and shit when it comes to Communist atrocities, but when it's time for the Fascist atrocities everyone has to stand up and yell HITLER HITLER HITLER. Precisely like a five-year-old.
It's just a sort of national lookin' after #1. We naturally ignore the sins closest to us and focus on those of others. Left is "self" and right is "other." Otherwise, we would need to express genuine collective guilt rather than dime-a-dozen collective contempt.
I understand why left-wing violence, lawlesness, etc are tolerated or encouraged - I'm asking why you think corresponding with Kaczynski does not bring the same scorn upon a person as corresponding with Rudolph would. Is it because people don't understand Kaczynski's intentions/thoughts (indeed, as reading the comments on this post would easily demonstrate)? Is it because they fundamentally agree with him, regardless of his contempt for liberals? After all, destruction of technology / industry has traditionally been a left-wing project in the U.S.
The first half of your first sentence answers the second, doesn't it? You could ask exactly the same questions with regard to John Brown - another classic American figure.
The supposed distinction between the "moderate" and "extremist" left is wildly overblown. There's no social exclusion, etc, in either direction. Nobody cares or is surprised about President Obama's association with Bill Ayers. Or, for that matter, Thoreau's with John Brown. Again, there's really nothing new here.
(I do think it's appropriate that in the nation of John Brown, we all need to walk through metal detectors to get on an airplane. Nothing could be more American than terrorism.)
