Cursory research is better than no research.
I'm reading his work now, but I don't really expect I'll have a sudden change of heart.
Edit: A more thorough examination of his works only reinforces my initial impression. His entire thesis is based on the construct that is civilization, which he himself calls a departure from the natural state which is governed by its own law of survival of the fittest.
Btw, I'm not saying rights are a bad thing or superfluous in any way. Having rights is definitely better than not having rights and I'd fight to maintain/regain any rights I think I deserve if someone tried to take them. I'm just saying that considering rights as something that comes from, or is inherent to, nature is a fundamentally flawed idea if you consider nature and civilization to be seperate things.
