Gendered Birthday Cards For Tots

I had to get a birthday card for a two-year-old (or perhaps for her parents, given her age), so I went to the local pharmacy-cum-trinkets store.  The cards I found were segregated by gender.  Perhaps not all of them, but the ones which gave an age for a young child were.  The cards for girls were all cuty-cuty-cuty and pink and purple.  The cards for boys had cars and Spidermen on them.

There's no way a two-year-old is demanding such differences.  Just pointing out for all those who believe that gender differences are mostly biological that we sure tend and weed and water that garden in which they grow.
