When women in the atheist movement still get sexually harassed by public figures, get rape and death threats, and when having a "no sexual harassment" policy creates a firestorm, all from other people within the atheist movement, the movement does need to be more pro-women and more pro-social justice.
False dilemma.
Social justice warriors are not the only kind of people on this planet who care about safety and well-being of other people. Also, feminists sometimes send death threats, too.
The sexual harassment by public figures certainly has to stop, the perpetrators have to be punished: legally when possible, and removed from positions of power within the community.
Giving more power to feminists and social justice warriors is not the only way to do this. It is one of the possible solutions, but not the only possible solution.
As Nancy said, what other movement that you could see becoming active in the atheist movement that supports this?
And yes, they send death threats too. But at a ridiculously lower rate than is currently done, considering many popular female bloggers say they get death/rape threats every time they say something controversial.
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.
