Bear with me here. There is an out-of-continuity backup story in, "The Joker: The Man Who Stopped Laughing," #4 that is intended to be funny with a dash of body-horror. The Joker angers the magician Zatanna and she casts a spell that makes him pregnant. He vomits up a sentient pile of mud that can shape-shift so it makes itself look like a young Joker in order to avoid the narcissistic psychopath from killing it. The whole thing is played for laughs. However, folks heard all kinds of crazy things about the story and got mad.
Some people think it is a story about the Joker being transgender and somehow having Batman's baby. To the credit of some sites, they realize this is silly (even TMZ can see the intended absurdity). Fox News totally missed the point, however, along with others who think this is some kind of, "Woke liberal conspiracy," as opposed to the Joker magically getting pregnant with sentient mud he throws up. I know a lot of people don't fully understand how babies are born, but they don't emerge as self-aware vomit.
There are no gender politics at play here, and even if there were, who cares? The Joker was magically made pregnant by Zatanna, puked up some shape-shifting mud, and more silliness will follow in the next issue. Chill out, people.
