A blogger tries to sum up the controversy between Brett Kimberlin and Aaron Walker:

So he [Kimberlin] runs into another dick [Walker] (who is more of the garden-variety sort, has lots of friends among the 101st Keyboard Kommandos because of a stint over at Patterico’s and is a lawyer), and like two subcritical masses of plutonium banging together, it results in a thermonuclear dumb-out. 

That about sums it up.  I find the controversy interesting for the First Amendment issues, but beyond that, the whole Kimberlin/Walker controversy is like a bad soap opera featuring watered-down and slight-more-admirable versions of Ted Kaczynski vs Fred Phelps, pointing fingers at each other and trying to desparately to see who can reach the lowest road possible.
