The majority of commenters agreed that women could not excel in math, due to biology and evolution. In Slashdot Science, the commenters were mostly grown men with science degrees. I was a nineteen-year-old girl with only a high school diploma and a love of science. They were more educated than me, and I wanted to learn from them.
Whenever I encountered a Slashdot article about science and gender, I read the comments, trying to learn more about myself. I felt sick to my stomach each time. I used mental gymnastics to reconcile my love of science with science-credentialed, male elders proclaiming with certainty that female brains were unfit for math and science. They were the experts, after all. I was only a young, female science student.
Math and science are hard. I worried that when I found something challenging in math or science, it was because I was a girl and lacked the mental machinery to understand it. (I thought of myself as a “girl”, because I was still technically a teenager.) I accepted evolution. Many times, I had panick attacks over the possibility that I had innate, hard-wired mental limitations. Before graduating with a science degree, I was unproven. There was no proof that I could be a science person, but I already saw mountains of scientific evidence suggesting that I could not be a science person. Unproven male geeks don’t struggle with science research telling them that they can’t do science when they start to try.
Only after I graduated with a science degree did I feel I had the authority to challenge Slashdotters. Only after I graduated did I feel like a real adult. After I graduated, I was livid, knowing that Slashdot commenters were merely conjecturing casually about my mental limitations, unwittingly crushing the self-esteem of my younger geek self.
Sexism on the Internet—especially discussion websites about science, computers, and math—are like guided missiles targeting and damaging the self-esteem of young female geeks. Female geeks are most likely to see male geeks discuss our alleged mental inferiority in math and science. Non-geek women are unlikely to see these comments, because they are not the ones reading Slashdot, Digg, reddit, Hacker News, techcrunch, or Ars Technica.
For many male geeks, conjecturing about women’s mental and career potential is just an intellectual exercise, and stating personal and scientific hypotheses about women as if they are scientific facts is harmless. For us, it is personal and disturbing.
I was cynical about Wikipedia’s openness to minority views in the comments of a previous post, 
There is sexism in tech culture. However, I continue to love tech, because I think of the sexism as a separate, unnecessary appendage to pure tech. I cannot think of sexism as intrinsic to or inevitable in tech, because then I would be either self-hating, or I would have to give up my love for technology. Maybe my personal ontology is compartmentalized thinking in order to survive as a woman in tech, but I think it’s also true.
In Surely You’re Joking, Mr. Feynman!, chapter You Just Ask Them?, Richard Feynman frequented a bar and desired to have sexual intercourse with the women there. He discovered that the women in the bar did not provide sexual favors in exchange for monetary compensation in the form of drinks. Although he gained a reputation for spending money on drinks for women, he was frustrated at the fact that the women did not consider alcoholic drinks to be payment for sexual services.
Some female geeks use the discourse of increasing female representation in science, technology, engineering, and math (the “STEM” fields) as a proxy for addressing sexism in geek communities. Because countering sexism against women does not directly benefit men, some women reframe the issue of sexism by appealing to capitalist values. They argue that if women are better represented in STEM fields, it would lead to economic growth and technological innovation (and that this can be achieved through efforts to reduce gender bias).
