God, people are stupid. You don’t develop an “evolutionary” preference for the blue of the sky just because it’s there and you look at it. The preference has to increase your reproductive fitness somehow. Are they saying that looking longingly into the sky makes more babies? I’d like to see the story they spin to make that work.

And at least the Virgin Mary bit has an honestly arbitrary source - Mary is commonly pictured as wearing blue, so it’s her color. Even if they’re using the color to signal “girl! girl here!”, no one says the girls forced to dress like Mary are doing so because they have an evolutionary desire to emulate Christ’s mother. I mean honestly, we have pink Nintendo handheld gaming devices because it hearkens back to our hunter-gatherer days? Men never needed to spot berries for consumption while hunting, so they didn’t pick up this love of pink? Berries would have been a special treat, like dessert, back then - they’re extra sweet, hard to find, and you’ve got to compete with everything else that wants them and can eat them before their short ripe period. Seems like if we’re hunting and gathering, the ability to find berries would be a skill prized by both genders.

This woman is so clearly talking out of her ass, it boggles my mind.

Of course, among my people (Roman Catholics), blue is a traditional color for girls because it’s the Virgin Mary’s color. So the poor kid just can’t win.
