How bereft of joy does your life to be to mock people who have "gender reveal" cakes? Tumblr's current feeding frenzy of "haha look at these weirdos who think gender has anything to do with genitals trying to force oppressive gender roles on babies" is making me very Sigh.

They're cute, harmless cakes, many of them beautifully decorated, at worst mildly amusing in their choice of boy/girl characterizations. There are a lot of pretty terrible parents in the world, but a couple (hell, even one parent) putting this kind of planning and excitement into something before the kid is even here? Sounds to me like they're prepared to be loving parents, and maybe you could just chill and think that's neat instead.
