Christina is talking about the atheist movement, not the set of all atheists ("atheist" is used there as a shorthand for "member of the movement;" maybe we need different words?).
Yes, I think it's a very poor choice of words to conflate a philosophical position with a set of people publicly arguing for it (and for other things as well).
And I'm not even sure we can properly say that there is an atheist movement. There are a few prominent atheists (Dawkins, Harris, Myers, etc.), plus various bloggers, who speak at atheist conventions, but atheists as a whole are not organized, and they have a variety of positions on many relevant topics (religious tolerance, personal liberties, etc.)
In contrast, IIUC, the LGBT movement is more organized, and, while not universally representative, has more support among the queer people. I suppose that most queer people largely agree on issues such as sexual rights, adoption rights, family rights, etc. After all, being queer refers to pattern of preferences and behaviors, while being an atheist refers to an epistemic state.
And if you're talking about a movement, then a call to be more inclusive is not a non sequitur at all.
It's not a non sequitur, but I don't think it's good advice. Intellectual honest discourse should be, IMHO, blind to gender, race, ethnicity, sexual preferences, and other group differences (unless these happen to be the topic of the discourse, of course). Affirmative action has no place in it.

I'm not sure the situations are all that different, except that "movement atheism" is younger. (I speak here mostly of the U.S., since it's what I know.)
Queers, for example, are significantly divided on questions of family rights. There are those of us who endorse the existing legal structure around familie...
One of the lessons highlighted in the thread "Less Wrong NYC: Case Study of a Successful Rationalist Chapter" is Gender ratio matters.
There have recently been a number of articles addressing one social skills issue that might be affecting this, from the perspective of a geeky/sciencefiction community with similar attributes to LessWrong, and I want to link to these, not just so the people potentially causing problems get to read them, but also so everyone else knows the resource is there and has a name for the problem, which may facilitate wider discussion and make it easier for others to know when to point towards the resources those who would benefit by them.
However before I do, in the light of RedRobot's comment in the "Of Gender and Rationality" thread, I'd like to echo a sentiment from one of the articles, that people exhibiting this behaviour may be of any gender and may victimise upon any gender. And so, while it may be correlated with a particular gender, it is the behaviour that should be focused upon, and turning this thread into bashing of one gender (or defensiveness against perceived bashing) would be unhelpful.
Ok, disclaimers out of the way, here are the links:
Some of those raise deeper issues about rape culture and audience as enabler, but the TLDR summary is:
EDITED TO ADD:
Despite the way some of the links are framed as being addressed to creepers, this post is aimed at least as much at the community as a whole, intended to trigger a discussion on how the community should best go about handling such a problem once identified, with the TLDR being "set of restraints to place on someone who is burning the commons", rather that a complete description that guarantees that anyone who doesn't meet it isn't creepy.
