I don't think there is any. Self-sacrifice and altruism are Christian virtues. To Rand, they are evil. Greed and selfishness are virtues in her system. Objectivism has a lot more in common with Satanism. In fact they are in essence the same philosophy.
Yeah, I saw that link. I checked it out and personally, I don’t agree. Rand didn’t care for Libertarians, even though they often use her arguments. I can’t imagine she would have embraced Satanists just because they found some common ground with her philosophy.
It’s like those journalists who called Trump a racists for _not_ denouncing David Duke. Or because a room full of supremacists gave Trump a Nazi-salute, he’s now some sort of neo-Nazi.
Rand didn’t believe in altruism or self-sacrifice, that’s true. But she wouldn’t stand in your way of charitable giving or charitable giving till it hurts—if that is what you want to do.
If you like science-fiction, I recommend Robert Heinlein’s _The Moon Is a Harsh Mistress._ IMO, He covers a lot of the same ground that Rand did in _Atlas Shrugged_ , said it better, and more entertaining in the bargain.
