I haven't thought about it much but I've noticed some of my friends call villagers a different pronoun then I thought they were. Like Rocket for example, my friend called them he & I thought they were a female villager. Not that it makes much of a difference.
this is something villagers did when referring to uchi villagers in new leaf - as far as i know they don't do it anymore in new horizons? i haven't seen it at least. but sometimes in new leaf, villagers would refer to uchis with male pronouns.
To be honest all I really care about is if they are cute or not and having every personality. When I make my island I do like to make sure my population is half and half because the game was designed for each sex to have select personalities and i care very much about those personalities for the sake of having a diverse town, but I their gender doesn't matter really. If they still had 8 personality types and no genders I'd still play the way that I do. I just don't want every villager of mine to give me the same like 5 lines because they are all Lazy or Snooty lol
I've honestly never thought about it much. I do know that I am more likely to call villagers with lower voices male if I don't know if they are a boy or a girl.
I pick mine based on personality because I want at least one of each, so I pretty much have each villager's personality memorized, and I guess that means I have their gender memorized by extension. It's not something I think about much though, it's hard for me to see an animal as feminine or masculine because they're a completely different species.
I can relate! I'm nonbinary too. I don't really consider whether they seem androgynous when I choose villagers, not on purpose anyway, but I do find myself drawn to villagers who seem a little more androgynous. For example, I love Fang's fabulous eyeshadow, and it's part of why I became so attached to him :3 I also loove Velma, for multiple reasons, but partially because she's the only female goat with a beard, and I headcanon her as a trans girl.
Also, when I was a little kid playing WW, for some reason I was convinced that Kid Cat was a girl. I loved that she was a girl who worked out too. I have no idea how I came to that conclusion. Later on I realized of course that the animal personalities are genderlocked, but sometimes I still refer to Kid Cat as 'she' out of habit '^_^
