RE parts you quoted. Of course they look bad, because they've been ripped out from context.
Race:
http://lesswrong.com/lw/kk/why_are_individual_iq_differences...
This is an article asking, to quote: "But why is it that the rest of the world seems to think that individual genetic differences are okay, whereas racial genetic differences in intelligence are not?". Yudkowsky seems to argue that making big controversies around whether there are, or are not, differences between "races" is missing the point; it's just one of many variables and we should focus on fixing intelligence disparities for everyone.
Society:
http://lesswrong.com/lw/ub/competent_elites/
This blogpost is marked as controversial from the get-go. It covers a quite interesting theory IMO - that the very common meme, which says that elites are stupid and evil, is in fact wrong. Eliezer argues towards a more socially uncomfortable opinion - that elites are, in fact, smarter and better at organizing things. Given that this is a belief most people are heavily biased against, it actually may be the "thing you can't say", per PG's essay at http://www.paulgraham.com/say.html.
Story:
Geez. This is a sci-fi story. Moreover, it's explicitly designed to fuck with reader's moral intuitions. That's its entire point. Personally, I find it fun and insightful, but it is heavy. You can read the whole work here:

And to be clear. I'm not idolizing Eliezer. He's just a man who thought a lot about some stuff, and wanted to share it. He sometimes gets it wrong (and, as opposed to many, has at least the courage to admit he was wrong). But I absolutely hate this kind of bullshit pseudocriticism when it's directed against anyone - be it my friend or enemy, be it someone I admire or despise of. Eliezer is not beyond criticism, but we can do better than that.
