iKnighty: You’re quite right about the origin of the name. My mistake for neglecting to mention that.
Also, yes hedonism, individualism and vengeance are encouraged. Indeed, it’d be a very short book if it merely said ‘do as you like’. However, it’s made very clear in the book that these are not dogma, they’re more attempts to counter religiously/socially imposed inhibitions so that you’re left free to act on your natural impulse.
This doesn’t mean that you belt everyone who looks at you funny, it just means that you don’t arbitrarily prohibit yourself from doing so.

You’re right in a sense; we oppose religion, but mainly for its dogma. We encourage recognition of humanity’s primal nature and religious ceremony/community do cater to a basal human need and therefore so do we. (Edited)
On your second post: That you don’t see much power in the church is partially myopia and partially signs of progress on our part. The church can still, say, outlaw gay marriage and abortion by mobilising the flock. But you’re right, they’re weakening.
The difference you describe between man and beast is not one of type, but of scale. Chimps can do anything men can do, just a lot less competently. They’re said by primatologists to be roughly equivalent to a four/five year old human
It may seem self-contradictory, but no more than Christians calling men lowly sinners and made-in-god’s-image in the same breath. We are only our own gods since we control our destiny, but we’re still animals and denying that or the implications of that seems silly.
On free will, I agree that it maybe an illusion, but that doesn’t mean that it’s not me defining my destiny, it would just mean that I didn’t have a choice in defining my destiny.
