Let me have a go at this.
Fellow effective altruists! It is your moral duty to familiarize yourselves with biological realities, many of which are relevant to deciding the morally optimal course of action. For example, "findings from twin studies yield heritability estimates of 0.50 for prosocial behaviours like empathy, cooperativeness and altruism". (source) Please take this into account when deciding whether to have children.
Fellow HBDers! It is your moral duty to take up the white man's burden and donate to GiveWell today. If giving money directly to poor people in Kenya doesn't seem paternalistic enough then go for the deworming options.
Have I successfully alienated everyone yet?
Actually, that was pretty good; pithy and introduces actual object-level issues to debate rather than abstract ideological concerns.
Please take this into account when deciding whether to have children.
This is pretty important actually; you see a lot of EA talk around here which basically assumes children are fungible ("If I don't have any kids, but spend the money to save n African kids then I'm in the clear!") without taking into account that those n kids will likely need > 2n kids-worth of aid themselves in a few decades and you've squan...
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.
