And I remember reading a post by Yudkowsky who downright called objectivism a cult.

That post also contained an explanation why. It listed specific things Ayn Rand did wrong. (She admired a philosopher from two millenia ago, but ignored recent research related to her central topics. She wanted to be rational, but didn't know how exactly, and thus couldn't teach her followers. So she made "rationality" an applause light, and her followers admired her, but didn't know how - or even aspire - to surpass her.) And there are also a few nice things in the article, when deserved.

Compared with that, you merely did a drive-by shooting. (Which does not contribute to a reasonable discussion.)

EDIT: Connotations disclaimer: I listed a summary of criticism by Eliezer to show that Eliezer provided specific criticism in his article. It does not mean that I agree with all of it. It means that I support that style of debate, as opposed to the drive-by shooting in this article.

Just have some people like Ayn Rand spread ideas like unmitigated greed being good, and presto! You get a whole bunch of people who now feel justified in spending all of their combined human ingenuity to hurting each other in an attempt to get ahead in society.

When you say stuff like this, to a person who has read Rand you sound like a creationist blaming Darwin for racism and ethnic cleansing. Rand was a proponent of peaceful, honest, mutually beneficial human interactions, not of a "might-makes-right" philosophy. Among other things, Atlas Shrugged features a critique of crony capitalism.

(Disclosure: I have not downvoted you. I am not an Objectivist, but I have read just about everything Rand wrote and am probably more sympathetic to her ideas than the average Less Wronger.)

Do you see how you went from character assassination of Rand, to character assassination of those who downvoted you, to character assassination of me. Is that what you consider "terribly mature"?

And no, I didn't downvote all your posts, just the original and your first reply to me, which one should expect given my disapproving responses.

I now have lost a significant amount of karma for having posted an article that I did my best on.

Very disappointed in Less Wrong as a rationalist community right now.

Maybe your best just wasn't good enough, and that is not a moral failing of the LW community.

But I did gain more sympathy for the point of view that many problems in the world really look like they are the result of malevolent intent

You already have way too much sympathy for this view.
