This is just my opinion as a white person who's never experienced racism and has lived a life of white privilege- the season is extremely racist while trying to paint itself as anti-racist.
Goat gets its throat cut (seen and heard), snake is sliced open (seen only), chickens are killed & head chopped off (seen and heard, very gruesome), mouse gets caught in mouse trap (heard only), frog gets sliced open multiple times (seen and heard).
The word "ra*e" is mentioned in episode 1, when the police comes to the witches home and in the beginning of episode 4. And in episode 7 at 5 minutes. And episode 8, at 2:24 minutes. That's all I know till now, but I'll write another comment if I recognize more situations.
madison is raped by a bunch of frat boys in the first episode, zoe walks in on them and finds them. this scene is skipable but referenced a couple times throughout the show
AHS season 3 episode 4 at around 42:15, the scene cuts to Delia hunched over a toilet bowl, there is audio. If you are sensitive to vomit and retching sounds you will want to skip from 42:00- 42:01. I'm currently watching this season and I will update if I find anymore scenes like this.
the witches convince fiona to attempt to commit suicide. she swallows many pills and very nearly dies until she is forced by a ghost to vomit them all up
A character is made immortal, buried alive, and told she'll be there basically until the end of time. The character is absolutely repugnant in every way but the scene BADLY triggered my claustrophobia.
A male ghost watches a girl from childhood until she is an adult without her knowing. Many scenes are shot as if someone is stalking/watching the characters
SPOILER WARNING: There is a large age gap but not in the typical way. There's a spirit in the house known as the axeman (M 50ish). When he's released he goes to find adult Fiona Good. They meet up and flirt and have sex. He then reveals that he's been watching over her like a father figure since she was 8 years old but when she turns like 20 or something he falls in love and watches her strip and stuff without her consent. I just personally found this really creepy and if this is a trigger for you, how this is done will be creep you out too. I would just skip.
