Jasper was very clearly portrayed as being abusive, especially towards Lapis, and yet people adore her and a some even ship her with Lapis. There wasn’t any huge outrage/outburst at her actions and a few people were even trying to defend it. (Liking her as a villain or liking her character design is one thing, but refusing to acknowledge the fact that she is abusive is kinda :/ )
But then Pearl, who is coded as autistic and also seems to have a mental illness, gets this huge wave of backlash, with a lot of people calling her horrible, a monster, saying they hate her, etc…when she does something wrong as a result of her projecting/unhealthy coping mechanism because of her mental illness, grief and trauma. Yes. What Pearl did was wrong, and had abusive tones (teaching Connie that she was nothing and Steven is everything - although this is also a projection of Pearl’s opinion on herself which is another matter). But the absolute demonisation of her character is kinda :/ . Especially when its been shown that, once she realised what she did was wrong, she apologised and is shown to be trying to fix her mistake/get better.
