I’m not sure what you mean by “feminist” in the sentence “Over-privileged rich white males, who make up the majority in atheism, don’t want feminists around,” but if by “feminist” you mean “me,” that doesn’t surprise me, because your perceptions both of American society and atheist groups specifically are unhinged. I’ve never seen women drummed out of an atheist meeting. Indeed, there was an FFRF conference I went to a few years back where Julia Sweeney was everyone’s favorite act, but people walked out on Christopher Hitchens. Based on that experience, I would say that it’s safer to be a woman in the atheist movement than to think the Iraq war was a good idea (and I’d bet it’s safer than being pro-life).

The thing about needing a hard-science Ph.D. to be accepted in atheist groups is also bonkers. If the top-four atheist authors right now, only one has such a Ph.D. Dan Barker, who leads one of the largest (if not the largest), atheist groups in the country, is a college dropout for christssake.

Finally, while life in our society isn’t completely fair, it’s not true that being poor makes a Ph.D. unattainable. I’m in grad school right now because an admissions committee thought I was a good enough student to be worth paying to come to their school. I did have parents who could help me through undergrad, but the background of people at our program isn’t uniform–one of my friends grew up having to help shovel animal manure on his parents’ farm.

Finally, some advice, though you probably won’t listen to it: you come off as someone who feels like a failure at life, and is coping by blaming other people. Why such an approach may be tempting, other people will sense the negativity and think “I have to get away from this person,” and it will be a barrier to you getting anywhere in life.

They don’t want to have to think about things like women’s human rights being violated across America everyday, every time a woman is denied contraceptives or an abortion.

They don’t want to hear the feminist voices from the trenches of “the Other America.”

They don’t care about the feminization of poverty and lack of money to afford tuition for college and grad school — never mind a science degree.

Anyone who doesn’t have a PhD in some science field, and who is poor and female is not welcome. Lack of money and privilege to get a PhD in one of the “hard sciences” automatically renders one worthless and of no value. If you doubt this, you might want to read more here:

Women are not seen, even by atheists, as being human enough so that injustice and harm to women matters.

The women whom you would think would be welcomed into the limelight of atheist conferences, are hard-core feminists…women like me for whom a ticket to grad school was as unobtainable as a day trip to Sedna. Because I’m poor. Like most women across America.

There’s a lot of over-privileged penis inches invested in the “New Atheist” movement. And when money talks, it does so from white male mouths at the apex of the social order.
