Well, you should see how it is with birds

"How is your bird, is he fine?

• Yeah, he just suddenly laid an egg so we need to check his calcium intake

• Ah, so it’s a she? Did she make more than one egg? Is she healthy?"

And if you keep on saying a non-specific “he”, you get the “you’ll need to get used to saying ‘she’ now”

The only reason people switch pronouns easily with animals is when it conforms the idea of “sex = gender”, if your dog has male genitalia, and you tell people “yeah I know but it’s still a she”, people are going to look at you weird and ignore what you said.

Tldr: people are stupid boomers
