Clicked through from bunnyjadwiga's LJ. I feel this pain, deeply. I switched to librarianship after a master's in religion, and had planned to go into the info architecture/tech end of the job. I removed myself after the first round of summer classes because the constant commentary from the male students in my programming class just wore me down.

I get tired of the fighting, honestly. Like you, I get tired of explainaing myself/defending myself/beating my head against that particular brick wall. And then I often feel guilty, because I am one of the people willing to speak up. But Dorothea says it all so much better....
