What would life be like for a baby raised without gender? Would they feel confused or free to just be their truest self? Would they be accepted by other kids, or ostracized?

In 1975, Ms. magazine ran a short "fairy tale" that imagined such a situation: "The Story of X," written by Lois Gould, recounted an "experiment" where two loving parents decided to raise their infant without any discussion of its gender.

Baby X's parents are instructed to buy plenty of toys and clothing for both boys and girls and to let X play with whatever they prefer. They're also instructed not to tell X things like, "Brave little Xs don't cry," or "Good little Xs never get dirty," but to just let the child learn and grow on their own.

It's a morality tale, so there's some drama (especially when X goes to school) and a lesson at the end—but it was pretty incredible stuff for 1975, when contemporary views on gender norms and identity were in their infancy.

Now, more than 40 years later, the story of Baby X is still incredibly relevant: In 2012, a pair of UK parents who attempted to raise their child without gender norms faced severe backlash, including calls for child services to get involved. Just last year, parents threatened to boycott Target after the chain began to phase out gendered toy aisles. (Of course, it's decision to offer gender-neutral bathrooms sparked even more outrage.)

Brendan Bradley has directed an 11-minute animated version of "The Story of X" that's both beautiful and poignant. Be forewarned: If you were ever shamed for liking the "wrong" toys or clothes as a kid, it'll get you right in the feels.
