[menacingly]

I agree with this, and hadn't thought of the clear problem in your last paragraph.

I have 3 daughters. They all have at least a slight preference for stereotypical colors, but one will actively shun products she doesn't find frilly enough. Her interest in babies and glitter is borderline militant, and I am certain a lack of bright colors would disengage her.

I can't believe articles like this are comfortable lumping "girls" in a single group with a consistent set of preferences.
