I flat-out disagree that power corrupts as the phrase is usually understood, but that's a topic worthy of rational discussion (just not now with me).

The claim that there has never been a truly benevolent dictator though, that's simply a religious assertion, a key point of faith in the American democratic religion and no more worthy of discussion than whether the Earth is old, at least for usual meanings of the word 'benevolent' and for meanings of 'dictator' which avoid the no true Scotsman fallacy. There have been benevolent democratically elected leaders in the usual sense too. How confident do you think you should be that the latter are more common than the former though? Why?

I'm seriously inclined to down-vote the whole comment community on this one except for Peter, though I won't, for their failure to challenge such an overt assertion of such an absurd claim. How many people would have jumped in against the claim that without belief in god there can be no morality or public order, that the moral behavior of secular people is just a habit or hold-over from Christian times, and that thus that all secular societies are doomed? To me it's about equally credible.

BTW, just from the 20th century there are people from Ataturk to FDR to Lee Kuan Yew to Deng Chou Ping. More generally, more or less The Entire History of the World especially East Asia are counter-examples.
