True that. At this point, the how we should focus on isn't how it happened, but how it can be resolved. I think that's the root we should be digging at here.
Can you see anything? What does it say? A lot of the people using kitty and pup and bunnyself pronouns are neurodivergent minors. It is a very common neurodivergent experience to feel a disconnect from being human and from the societal expectation of the gender you were assigned at birth. When you have this intersection of feeling a disconnect from the societal expectations of gender, whether you're [neurodivergent] or not, a lot of people have this experience who aren't ND, it's just very common with ND people. When this intersects, you get nounself pronouns and animal nounself pronouns. It's some sort of Leftist Newspeak. I can't decipher it.
