Here's a good reason: your entire comment is judgmental and assuming. It's not about hearing "hey, good job girl! Have a cookie!" It's about not hearing "your code is badly formatted, didn't you go to CS school?" instead of "that was a good refactor there, but you'll find it easier to read and share if you indent". Women have just grown up in different kind of group dynamics - and while women can be horribly nasty to each other in artificial groups, it's usually not the case when they choose to work together independently.
