If we're allowed to discuss genetically mediated differences with respect to race and behavior, then we're also allowed to discuss empirical studies of racism, its effects, which groups are demonstrated to engage in it, and how to avoid it if we so wish. If we're allowed to empirically discuss findings about female hypergamy, we're also allowed to discuss findings about male proclivities towards sexual and non-sexual violence.
Speaking for myself, I would be happy to see a rational article discussing racism, sexism, violence, etc.
For example, I would be happy to see someone explaining feminism rationally, by which I mean: 1) not assuming that everyone already agrees with your whole teaching or they are a very bad person; 2) actually providing definitions of what is and what isn't meant by the used terms in a way that really "carves reality at its joints" instead of torturing definitions to say what you want such as definining sexism as "doing X while male"; 3) focusing on those parts than can be reasonably defended and ignoring or even willing to criticize those part's that can't.
(What I hate is someone just throwing around an applause light and saying: "therefore you must agree with me or you are an evil person". Or telling me to go and find a definition elsewhere without even giving me a pointer, when the problem is that almost everyone uses the word without defining it, or that there are different contradictory definitions. Etc.)
Here's some empirical research on the actual causes of the pay gap. Executive Summary: The majority of the burden of child rearing still falls on women, and this can be disruptive to their careers prospects, especially in high paying fields like law and bussiness management; childless women and women who work in jobs that allow for flexible hours earn incomes much closer to parity.
A long blog post explains why the author, a feminist, is not comfortable with the rationalist community despite thinking it is "super cool and interesting". It's directed specifically at Yvain, but it's probably general enough to be of some interest here.

I'm not sure if I can summarize this fairly but the main thrust seems to be that we are overly willing to entertain offensive/taboo/hurtful ideas and this drives off many types of people. Here's a quote:
The author perceives a link between LW type open discourse and danger to minority groups. I'm not sure whether that's true or not. Take race. Many LWers are willing to entertain ideas about the existence and possible importance of average group differences in psychological traits. So, maybe LWers are racists. But they're racists who continually obsess over optimizing their philanthropic contributions to African charities. So, maybe not racists in a dangerous way?
An overly rosy view, perhaps, and I don't want to deny the reality of the blogger's experience. Clearly, the person is intelligent and attracted to some aspects of LW discourse while turned off by other aspects.
