Actually, the Klan being against them doesn't surprise me. The Klan thinks of itself as patriotic and, except when the National Guard goes after them, is generally pro-military. Phelps' antics at servicemen funerals is probably what led to the above.

Also, just occurred to me that it might be notable that these days we have the ultra-so-far-off-to-the-"right"-that-space-time-curvature-may-actually-have-them-on-the-"left" attacking servicemen, whereas back in Vietnam it was the left who attacked such. These days, save for ridiculous extremists, seems people are of the attitude "We like/hate the policy that has you in the field, but we'll at least respect the grunts who have to carry out that policy".

And finally, I guess if Fred Phelps ran against David Duke for Louisiana Governor, the old "Vote for the crook, it's important" slogan would have to change to "Vote for the Klan Wizard, it's important". : -)
