I think the actual situation is something like this.
Eugine believes that there are systematic (statistical) mental differences between men and women, between black people and white people, etc.
I think the LW consensus on this, in so far as there is one, is that there probably are such differences.
I suspect most LW participants would estimate smaller differences than Eugine would.
Eugine seems to love to talk about these differences and to trot them out as his preferred explanation for anything anyone might otherwise explain as racism, sexism, etc. Most LW participants do not have that preference.
Eugine believes that departures from traditional norms of sexuality and gender are Bad: boo to homosexuality, boo squared to transgenderism, etc.
I think the LW consensus on this is squarely against him.
And those are pretty much all the issues that Eugine posts a lot about. He may well have strong and/or interesting opinions on many other topics, but it seems that what he mostly wants to talk about is the inferiority of black people and the contemptibility of transgender people. (This wasn't always true. Compare the first page of The_Lion's user overview with that of, say, Eugine_Nier's.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
