It wasn't an argument, it was a side comment, supporting her approach (similar to one of many of my friends) and to some extent mocking the (culturally implicit) premise that one should align with one's own gender[1], see in e.g. "[...] and how none of the other girls in her class understood anything she was talking about". Would ever a tall person said "but none of tall people at my high-school can understand my jokes"? [1] And to some extent supporting also: "It’s funny because the evening started out with a lady giving a speech about how the IT industry is alienating women. But for some girls, it feels like women are alienating the girls who want to be in IT."
