Like I said, I'm uncomfortable with They as a pronoun. You should only use it/its if someone tells you its okay, but there are a lot of people who use it as a pronoun. There are some people who use it as their ONLY set of pronouns.
"It isn't. It is like calling someone a "Thing" Use them, not it. Don't be a clown. Be them." doesnt sound like saying we can use them if we want to me.
