Catering for everybody?

I posted last October about Brighton and Hove's decision to do away with gender titles (Mr, Mrs, Miss and Ms) on the grounds that forcing people to chose a title was unfair on transsexuals.  But of course this can be seen as equally unfair on those who are certain of their sexuality, and is a recipe for confusion generally, so the council have come up with a compromise - official forms will continue to have tick-boxes for Mr, Mrs, Miss and Ms, but will also include a box labelled "Mx" for those who do not wish to be classified by gender.  Apparently there are some 40,000 of what it seems I must describe as LGBTs in Brighton, so it seems a reasonable enough move.
