First of all, the OP wasn't commenting on the UI's "worth," he was using "girly" as an adjective to describe the UI's color palette. If you've ever been to the Barbie aisle at the toy store, you know that iOS 7's color palette is, indeed, reminiscent of the color palette favored by little girls.

"Misogynistic" means, "reflecting or exhibiting hatred, dislike, mistrust, or mistreatment of women." OP has an eight-year-old daughter. I doubt he hates her. And it's not misogynistic to wish that his smart phone interface wasn't colored like her toys.
