I think my representation was accurate and the sections you quoted rather support that. So some women felt like they got assigned sucky roles in group projects. But so what? Men get assigned sucky roles in group projects too. Every group project has that problem: some roles will be perceived as more desirable than others. There was an assumption there that the girls "sentenced" (gosh, what emotive language) to some other role simply because they were girls, and not because they were simply less pushy personalities in general. But no evidence is provided either way - they never asked the men why they did that, or if they even perceived the women as upset. Maybe an assertive woman would have steamrollered shy men in the group, I've seen that happen. Sexism is asserted as the cause and, as is always the case, that lazy assumption passes unchallenged. In another case, the women were complimented on their appearance by a man, something that happens in every work environment and every job around the world. This is related to gender ratios in programming specifically, how? The last quote - I'm not even sure how that's related to sexism. It appears to show a man enjoying the studies. I guess if women perceive things like the internet as not "contributing to society" that would be one of the non-sexism related problems women cause themselves. OK, sure, if they believe that, that'd explain some of the gender disparity, but again - so what? Lots of men believe the opposite. If true, it's a self-imposed handicap that women can discard anytime they like. Besides, I'd much rather work with people who believe their work has a higher purpose than people who are simply ambitious!
