The issue is that there is a nose, an ear, a lung, an anatomical heart emoji. None of which I imagine was lobbied for as enthusiastically as the uterus, which lets face it, is regulated and legislated and regularly menstruated far more than a penis (or ear, or lung). And was actively requested, by large numbers of people. But denied.
There's no issue with a man in a wedding dress per se, but are you suggesting there's a greater demand for that than for the apparently unacceptable uterus?
So the priority order goes
Ear yep
Lung deffo
Man in veil of course
Nose naturally
Mx Santa great idea
Uterus? F*ck no. What a repulsive thought, who would want to see THAT?
