I identify with libertarians, I'd not call myself a subscriber to their entire philosophy. I'm in the centre, as ever (Some right-wing ideals, some left, some in the middle).
As for benevolent dictators, there's a difference between mortal dictators that can be corrupted and the one true ruler of all existence that is morally perfect. Besides, anyone who knows anything about God and free will in the Judeo-Christian tradition would be well aware that free will and the right to choose is one of the prime blessings of mankind.
A benevolent dictator is the best kind of government possible, especially if they support essential freedoms (Speech, for example). The better educated this leader, the better they can rule, especially if they're morally perfect, and if they have unlimited power, well... Logically, an omniscient, omnipotent, morally perfect leader is the best leader.
However, we lack any mortal leader who has these three qualities, so the best we can do is try and develop the best government possible with what we have.
