That last line! Clearly demonstrates the ideological leanings of the project.
To us grown ups it simply sounds all wrong to refer to a known individual by a plural. So efforts are being made to indoctrinate children into the new religion.
To the previous poster asking about names like Chris, I would not naturally use they in this case I would naturally ask is Chris he or she, or is this a male or a female Chris before continuing unless I felt able to guess from the context.
I agree with a previous poster that eventually those who identify as the opposite sex will find that tricky when non-binaryism wins the day as I suspect is most likely. Human societies don’t function by asking individuals if they are male, female or neither. How we are perceived by others and society at large has never been up to us as individuals to dictate in the whole of human history. We look and know almost instantly in almost every case, man or woman, boy or girl. If we are forbidden from acknowledging sex then imposing a non-binary identity and they-themming everyone is where we are headed with mixed sex facilities in schools, sports, prisons, hospitals and everywhere else. It begins with using they-them for all babies and young children on the basis that they haven’t chosen (ideologues might say discovered) which sex based stereotypes they most align with yet.
Sex segregation makes sense in a variety of circumstances, gender identity segregation has no more rationale behind it than separating people based on star signs, that being the case it won’t be justified for long. Everything will be mixed sex or “gender neutral”. Eventually that excludes women and children from public life due to safeguarding issues, harassment, intimidation and humiliation.
