thats sexism. when your future daughter in their mid-teens announces they're trigender ("the feeling of having three simultaneous or fluctuating genders"), you may quietly think wtf?
really the problem with doing that way is there's no plaudits gained from virtue signalling. the "ladies and gentleman" address is infrequent, it doesnt fit in the normal pattern of announcements: "the next train...", "in this time of heighten security...", "the Central line is buggered..."...
you may jest, theres far more deaf people than those with gender issues.
i cant say i recall a "ladies and gentleman" announcment, wouldnt notice this policy change. and theres the thing that grates with me, why this needed to be announced, to wave a great big flag of rightousness around?
