I wonder if the problem would cease to exist for some of those who wish to change if society treated people as PEOPLE not M & F in areas where gender is irrelevant. It always seemed ridiculous to me that before you can chat to a new mother about her baby you need to know whether to say 'he' or 'she'. I suppose I might get used to 'they' in the singular, 'Ms' doesn't sound as clumsy now as it did 50 years ago.
Society changes slowly.
Luckily I was always treated as an individual.
Mo short for M...? (my internet net was unintentionally genderfree but I'm glad it is)
