Way to go on being an Objectivist. Even if you aren't religious, other people are important, and should be important in your life. The social contract exists for a reason. You don't have to believe in a deity to follow it, and you should still follow it even if you don't believe in higher power.
I'm confused about what the connection between this and his statement of his beliefs. He also says that he believes in protecting the people he loves - clearly he views other people as being important. The primary thing is that he views himself as the most important thing in his life. I don't blame him for that, I think self preservation is something everybody posses and it's not a negative quality. Hating enemies is fine too, that's why they are enemies. If you didn't hate them they wouldn't be enemies, they'd be friends, or just people you didn't have any positive or negative feelings about. I'm sure many Christians hate people and have enemies too (except Quakers maybe), the difference is hate is probably considered a sin and they apologize for it, whereas the Satanist does not feel a need to apologize for hating someone.
However; I have two issues here. Once is not asking for forgiveness for wrongs committed. This sounds a lot like "If I do something wrong, I shouldn't apologize." I think that if you wrong someone, you should apologize. If you know you did something wrong, then you should have a natural desire to make amends, otherwise you don't really think you did something wrong. If you don't want to make amends, then that means you have internally justified your action, in other words, you don't really feel you've done something wrong.
So my first issue revolves around not asking for forgiveness when you know you've done wrong. I think a fundamental part of knowing that you've done wrong is desiring forgiveness, otherwise you have not truly committed something you feel is wrong.
Hating weakness is my second issue here. It depends on what is meant by weakness and what you mean by hating it. For example, I might view poverty as a weakness. I don't like poverty. So therefore you could say that I hate weakness too. My natural reaction to people being in poverty is to want to help them out of poverty. I am then addressing that weakness and making it stronger, and we are all better for it. Does the Satanist feel different about this?
