The Zizians believe in IQ, that animals are ethically equivalent to humans, that all people contain exactly two personality cores corresponding to the two hemispheres of their brains, that every personality core is either intrinsically good or intrinsically evil and less than 5% are good. They believe in violence as a form of mutually assured destruction: you should always escalate every conflict to the maximum in order to dissuade hypothetical agents from blackmailing you. And the stuff about Skynet.

I think to understand properly it should be recognized that while the personality-core stuff is out of left field, all of the other beliefs are pretty much just logical conclusions of mainstream rationalist thought. For instance Yudkowsky has to repeatedly explain that he's not in favor of violence (except when he's advocating for bombing data centers) precisely because it's really easy to reach that conclusion from what he's written. The Zizians mainly differ by reaching that logical conclusion and being willing to act on it.
