This exists in more than just the startup world. I was in a meeting today where a technology leader said, "Let's have X take the meeting notes, she's a woman." This person also had her administrative account set to a pathologically trivializing username.
I think the term "microaggression" gets overused, but the story referenced in the article says that what's important about the person is her gender, attractiveness, and marital status. To the point that her "lucky" spouse deserves special recognition. What?!
