Pronouns: The Issue of Labels
I think that most people would prefer to be referred to as 'he' or 'she', but a few like the singer, Sam Smith, like 'they'. Probably those who use 'they' are trying to make a statement and if everyone was referred to in that way it would even take away the possibility of such a statement. Generally, I think it is highly unlikely that enough people would choose to be called referred to as 'they'. One art is to try to write or speak without using pronouns at all; it is extremely difficult and has to involve repetition of the person's name. In writing a sentence referring to a general human being rather than a specific one, I think it works to use the term they, rather than clumsy use of he and she.
Aside from pronouns, the whole question of titles is another related one, and I really can't see how they serve any purpose at all. It used to be the case that titles not only showed which gender a person is but whether a person is married or not. However, a lot of women use Ms instead. I believe that this was controversial at first. The writer, Zoe Fairburns, wrote a short story about how she was one of the first to take this on board and described how she was on a bus and how the bus driver was querying what this meant, as if there was something strange about her sex. One recent addition which I have come across is some people have started using the term Mx to be gender non specific. Pronouns are necessary because we have to refer to people, but I just can't see what purpose titles have at all and I think they are outdated and unnecessary.
