You say that, but I have had a pet snake since I was a child and because I was a boy child I assumed they were male. But once I got older it occured to me that I have no idea if they’re actually male or female (because sexing a snake isn’t as easy as with mammals) and it seems more likely that they’re actually female. But I’m not certain either way and I genuinely don’t care. So I’ve since started refering to them as they/them. My dad still points it out every time I do it. “Oh, you have multiple snakes?” It’s kinda weird considering he’s so progressive in every other way.
