Female-heavy sex ratio at schools.
One of the two times I’ve ever been approached by a woman in public was at UNC Chapel Hill in the late 1990s, which was already 60%+ women. The sex ratio was so skewed there that women were forced to act like men if they wanted any attention at all.
The few women that I knew there (or around there) mentioned how much it sucked. And yes, it sure does. When women actually get treated like men (despite what feminists say), 99% of them do not fucking like it much. And that’s because it’s terrible.
