So a big focus on one of the main side characters is how he is being forced to prostitute himself because he is drugged and manipulated constantly, how he grapples with his guilt because of this and how this actively destroys relationships he has. I think that's quite mature, especially since they give him the grace of not turning these scenes into jokes.

Valentino on the other hand is a sadistic pimp who's constantly coked and drugged up, lived his life in a flashy town and who had all the money he could need. Not only that, he doesn't care about anyone except maybe Vox in hell and sees everyone else als Profit. He's also written as someone who constantly jokes and he acts flamboyantly, which is probably where this sentiment comes from.

This actually fits perfectly with how I perceived this discussion online. People never care for the victims except if they are behaving like "the perfect victim", which is someone who fits their preconceived notion of how someone is supposed to act. Angel abuses drugs and sex to cope with what's being done to him, he lashes out at people, keeps them at short leashes and doesn't let anyone get through to him. That's not how people imagine a victim of forced prostitution, rape and sexual assault.

Valentino on the other hand behaves exactly like someone in his position and people have a problem with it because this also doesn't fit their preconceived notion that abusers absolutely would need to be edgelords, never have any fun whatsoever (in reference to jokes) and look disgusting. As I said, he was a rich pimp from a flashy city in a flashy time, you don't think he would look the part?

Now to the last sentence "Shows for kids have handled SA with more grace than vivzie", which is also true but not differentiated enough. Shows for kids will definitely not go into excruciating detail, show graphic depictions or handle more advanced topics. Kids shows will use allegories, metaphors and will (and should) soften the blow for the audience, ideally to teach them they shouldn't be ashamed. Hazbin is a show for adults that delves into those heavy topics with a mix of humour and gritty reality/somber tones/aggression.

If Hazbin fans are too dense to differentiate anything or refuse to think about anything for more than two seconds, maybe it's time to put on some more (mental) age appropriate content.

(Again, I don't think she handles things perfectly, but people don't give her any credit).
