I love singular they and the fact that even some people in the gender binary are starting to use it for any reason, such as not wanting to reveal their gender online, or not have their gender be such an integral part of them that it gets named in their pronouns, or just because they like the way it feels. This is the future and the English language and everyone who finds it confusing will adapt. Children will be born who grow up learning that it's normal and will not see it as confusing because it's just the way things are.
