You know what...
I went and looked this up because of this comment. I had never heard of "it" being used like that.
I've only ever heard it being used to specify something specifically as a non-person, or more generally a "being". So I thought it was literally defining it as a non-being.
So TIL. I wasn't trying to be prejudiced, I have literally never heard of "it" being anything other than specifically a non-living object.
So thanks for the chance to learn something interesting today.
And as I replied to another, I learned that today based on the wording of their reply.
So that's a new thing I know now. I still don't think "they" is binary though. It's is kinda the star example of non-binary.
But I guess I did exclude a pronoun that I didn't know existed. I thought the word was specifically calling the cat an object, so now I know better. It wasn't intentional, and definitely not meant that way (as in not meant to force or exclude, aka discriminate).
