I agree that it's not necessarily an example of misogyny in tech per se, but it's absolutely a contributing factor in why there are so few women in tech -- many first experiences tend to be as the sole female in classes with socially outcast males.
To begin with the state of tech education in public schools is absolutely abysmal, it takes a dedicated student with a strong interest in tech to tough it out through the school system, rather than being encouraged to go into tech by the school system. The media portrays programmers and other tech industry professionals as a bunch of lonely anti-social misfits who are almost exclusively male and either so exceeding stereotypically nerdy as to practically qualify as autistic, or else overweight and lecherous. These two factors combined mean that the vast majority of students, both male and female, decide to avoid the tech industry at an early age because either they believe the media stereotypes or else they take some tech related classes and are so appalled at the curriculum that they practically run to other professions.
When considering a career in the tech industry, going solely by the state of pre-college and entry level college tech courses, combined with the overwhelming media stereotypes around the tech industry, is it any surprise most women decide to pursue other fields?
