Hang on....
Trans women are women, yes?
And there's a long tradition of men dressing up as women for comedy and entertainment. Pantomime dames, drag queens, Cissie and Ada...men have dressed up as old women, young women, powerful women, tragic women, funny women, dumb women, stunning women, slutty women, nuns...they've dressed up as women to honour women, to affectionately take the piss out of women and to utterly insult and degrade women.
So....why should trans women, and only trans women, be off limits for men to dress up as? Isn't that kind of othering?
We need more men dressing up as trans women! I for one look forward to the first drag act whose character is a trans woman. Now THAT will be really challenging some stereotypes!
