|American Horror Story|

Copycats, Re-Creationists, and Tours (Oh My!)
The American fascination with transcendent violence and just plain weirdness was an inspiration to show creators Murphy and Falchuk while developing the series". It has been reflected in every season so far.
- The Eternal Darkness Tour is a disruption to the Harmons' lives, but also a path to understanding the strange events in their home.

Let's Talk About Sex
It's not all "death death devil devil evil evil" on AHS. OK, actually it is, but often it is specifically directed at those doing the nasty.
On American Horror Story, it is rare for any relationship to reach the post-coital cuddling stage.
- Constance makes both Hugo and Moira pay dearly for her husbands infidelity.
- Hayden practices her after-sex stabby stab on the already dead Hugo before using it to deadly effect on Travis.
- What started with a nice BJ ended badly for Joe Escandarian.
- Does it count if they're already dead? Ask most sexual partners of Oliver Thredson.
- Zoe Benson has an uncontrollable ability to kill whomever she has sex with. RIP Charlie. RIP Brennan.
- Kaylee is the second Alexandra Breckenridge character to catch a bullet after a sexual encounter.
- Troy, Bonnie's boyfriend, didn't even make it to third base before he was murdered by Twisty.
- Averted by Elsa Mars survival of a snuff film.
- Ditto the spooning scene between Jimmy and Maggie.
- Donovan and The Countess engage in occasional deadly sex with other people for their nourishment.
- Tristan Duffy has a scene with another man and the Countess almost after he is turned.
This may not be peculiar to American Horror Story, but a standard trope for any drama.
- Ben's affair with Hayden is the impetus that brings the Harmons to California and the Murder House.
- Hugo's affair with Moira spells death and a ghostly eternity for them both.
- Patrick's infidelities lead Chad to attempt spicing things up with a certain rubber suit.
- Larry's dalliance with Constance leads his wife to take her life and that of their children.
- With so much temptation in the house (Moira, Hayden and Elizabeth), Ben must constantly resist straying again from his vows.
- Vivien restricts her cheating to fantasies of Luke (unless you count her "willing" coupling with Tate).
- Regardless, Ben is convinced by Hayden to believe that Vivien's relationship with Luke is more than just a wet dream.
- Shelley's constant affairs lead her husband to have her committed to Briarcliff Manor for nymphomania.
- His belief that Alma is still alive with the ETs doesn't stop Kit from planting his seed in Grace.
- Even if unmarried, Carl's trysts with Shelley break a trust not dissimilar to infidelity.
- Though not in control of her body, Sister Mary Eunice's rape of Timothy Howard was cheating on her marriage to Jesus.
- It is unknown whether Pope Paul VI would have pardoned the Monsignor's tumescence, without which the rape wouldn't have been possible, or if it would have been considered a violation of the priest's own vow of celibacy.

- Hank cheats on Cordelia with Kaylee before putting a bullet through her head.

- Shelley steals a cucumber from the kitchens, and later hints it is not because she is hungry.
- Thredson encourages Lana to masturbate in front of Daniel as part of her aversion therapy. 
On most shows pregnancy usually means a cute new cast member to boost ratings. On American Horror Story it always portends trouble.
- When your husband cheats on you with one of his students, a miscarriage is not so strange to happen. Vivien Harmon knows.
- During Vivien's heteropaternal pregnancy, Michael "murders" his twin antepartum.

- Desiree Dupree suffers a miscarriage that leads to the discovery that she is all-woman.
- As if being attacked by a street gang was not enough, Shelby Miller suffers a miscarriage shortly after.
Either as a one-time thing or as an actual romantic polygamous relationship, three-way relationships are featured in all three seasons of American Horror Story.
- After arriving back home with Grace Bertrand and their son Thomas, Kit finds out his presumably dead wife Alma is still alive, and so is their newly born baby. And they all end up living together in an apparently happy polygamous marriage.

- Natacha Rambova no steps aside, rather seduces the female lover of her husband Rudolph Valentino.
Can't We All Just Get Along?
Striving for acceptance and harmony while the body count rises.
It is practically a mission of co-creator Ryan Murphy to challenge the homophobic worldview and its predecessor in ignorance, racism.
- Marcy's comments reveal a touch of both racism and homophobia.
- Comments from Tate and Joe Escandarian regarding gay ghosts (ghaysts?) Chad and Patrick aren't exactly politically correct either.

- Murder House
- Ben and Vivien are too tied up with their own issues to notice Violet's suicidal depression.
