Before the onset of the nuclear family, it was not so unusual for Anglophone households to resemble the extended families of their Latin American and Mediterranean European counterparts. Various combinations of bachelor & spinster siblings which continued to live together under the same roof were infrequently sported as characters in early movies. As late as the mid '70s, Rocky Balboa got his wife from just such an asexual relationship (Paulie Pennino's very strategy seemed to consist of making his sister Adrian feel like a loser so that she'd persistently stay with him).
Overstepping things a bit, since any Liberation:Incest operation would itself still be in tentative, fragile opening salvos... But going even further down the line to future SJW phases of normalizing today's lingering extremes... Norman Bates wouldn't quite be a fictional poster-child for necrophilia marriages with corpses, but keeping his mother's body preserved and ready at hand must count for something.

EXCERPT: Catherine Utley has lived with her sister Ginda for more than 30 years. The pair raised Catherine's daughter together and jointly own a house in south London. And they are among a number of siblings who want to be allowed to enter into a civil partnership.
When the idea was aired on Twitter yesterday by a Tory MP, he was met with huge outcry and accused of supporting incest and being "ridiculous". But civil partnerships for siblings is something which campaigners have long called for. "There's no real argument against it," says Catherine Utley, 59. "People are getting the wrong end of the stick."
[...] "She stood by me when I had my child in 1993," says Catherine. "I got pregnant and it wasn't planned and it wasn't possible for me to live with the father and so it would have been a complete nightmare. My dear sister's immediate reaction was to stand by us. We bought a house together to be close to our two brothers, and it was just a wonderful thing. She's been my rock, totally."
Catherine says there is a "special bond" for siblings who live together in adulthood. "She's like my other half, she's my best friend. I've known her since I was born. Some people don't get on with their siblings but if you do it can be a very strong relationship."
[...] Catherine and Ginda want to be able to enter into a civil partnership so they can enjoy the same inheritance rights as other couples who have formalised their relationship. "When my sister dies or I die one of us will have to sell the home to pay for the inheritance tax."
Catherine says it is a "glaring injustice" because civil partnerships are open to any two people. They don't need to be involved in a romantic relationship - they just cannot be blood relatives. Excluding siblings is pure discrimination. I could have a civil partnership with my next door neighbour, but I can't have a civil partnership with the person I have shared my home and life with."
She adds: "I'm not saying civil partnerships is the only way the inequality can be addressed, but it's the most obvious way. They could do something about inheritance tax by changing the rules."
