I believe what Catlin is referring to is in that very long, strangle explanation of his "reliegion." In there are sections that discuss why it's okay to take advantage of "lower" life forms (yes, he has names for every type) because, they are lower. There is a middle group who has the chance of becoming a member of the "upper class" but everyone is screwed. Period. It's late but tomorrow I will try to plow through that lovely piece of literature and give you page number numbers or something.
I think we all have to be careful that we don't turn Humble into something he's not.
