Also:

Getting a touch distracted with the horror film aspect. I've thought maybe my topic was a wee bit broad but fancied it'd be alright if I used specific enough examples. If it explodes over then I have a couple different directions I can reign in with, orrrrrrr not. Yeah.
But mostly: domesticated woman and castrating-female ---> biological women
M-to-F as stronger and less typically effeminate in terms of narrative power
Alright.

Having mentioned horror: I don't want to focus on the horror aspect of the transexxual, although that might be all but impossible. Yeah, there's the "Oh-balls-you-have-balls" scene in "The Crying Game." And yes, in "Psycho," the fellow does dress up as his mum and kill folks. And sure, " The Silence of the Lambs"--maybe that is a wee bit weird skinning women to make a suit for yourself.
But I want to focus on the human, gender-codings, not the ohmygoshshe'sgotapenisandaknife aspect of it.
The need to be loved, the maternal instinct, the self-conciousness all women feel, the over-protective, jealous mother, etc.
