It appears to me that DB is, to be frank, a crank. He has a certain view of the world that is firmly set, and I bet that it's pretty near impossible for anything to get through to him, not without medication anyway. I bet that moderator action will be ineffective, and will only result in his banning.
Now some people may welcome this, although seeing how MartinV continues to make his mess on multiple threads, as does Willow Tree (currently going by Cold Foreign Object) this seems to be within accepted norms for a certain class of people.
DB is not making a mess of other threads; he's confining himself to the one thread, and I think that anyone reading that thread should be aware of what they will be in for if they choose to participate.
Just my 2 cents (American).
Added by edit:
I'll also add that DB started the thread himself in order to expound on his particular madness.

Progress in human affairs has come mainly through the bold readiness of human beings not to confine themselves to seeking piecemeal improvements in the way things are done, but to present fundamental challenges in the name of reason to the current way of doing things and to the avowed or hidden assumptions on which it rests. -- E. H. Carr
