Joe:

You've sure posted a lot for someone who's not read the material. It may be that you simply have nothing to contribute... but, just sticking with Klein:

Can you make sense of his timeline? I'm not assuming I'm right and he's wrong. Are you?

eg: If Rastus Brown was a response to Louis-Schmeling II which produced a similar commotion 22 June 1938, it would be after the Run, Nigger, Run incident and your assumed timeline for Guthrie's racial epiphany would then be completely wrong.

Drop cudgel, pick up a calendar.
