Well....yeah, it pretty much is. And so am I. I have no desire to see Bakugou punished for his dickishness, personally, only seeing him grow beyond it. He's progressing nicely as a characters whose slowly learning that his power doesn't give him the right to treat others like shit. I mean, in case you haven't noticed, he doesn't do any actual bullying anymore. He recognizes the strength of the people around him, to the point where he was the only one who took his fight with Uraraka seriously. And he repaid Kirishima his money when he rescued him, expressing gratitude. Subtle expressions like his fear of the villains that capture him and his guilt over being part of bringing All Might's time to an end humanize him and give him more and more dimensions.
And that's all fine and good, but my problem is it's too slow. These things didn't need to happen over the course of 100 chapters. Todoroki, who has a fraction of the focus, has gotten better development.
He's never going to stop being an asshole, I think. It's a core tenet of his personality. And the narrative has no issue with that. It's more interested in growing other personality aspects rather than reducing his attitude. As such, it recognizes the value of his ambition to win and be the best, something that Midoriya does indeed lack in.
But that ambition to be the best is a message that runs counter to most of what we've seen so far. It's not about being the best, it's about saving people. Bakugou's obsession with the former is what made him so bitter when he sees someone he sees as "lesser" being able to better accomplish the latter.
MHA seems to have a pretty consistent message most of the time, but whenever Bakugou enters the scene, it suddenly turns into a mixed message.
If you don't like that it doesn't look like Bakugou is going to suffer for his bullying or that he is going to be converted into a nicer person, then idk, it feels like this is just not the narrative your looking for. You directly tying your desire to see karmic justice, or atleast your moral sensibilities about what should happen to bullies, to how you gauge whether something is good writing. Not all works do that though, and I generally prefer works that don't.
I got no problem with it when it's a straight comedy or when the story has a far more cynical message or hell if even it's not something the creator doesn't want to focus on. Vegeta never really got any comeuppance for his earlier actions which included A LOT of killing of innocents even beyond the farmer. He didn't lose his dickishness either, and I still loved him as a character.
But despite the fantastical setting, MHA does try to be relatively grounded and relatable while also trying to address stuff like what you mentioned. It's just an endless fumbling of the concept as it seems Horikoshi is just super averse to breaking the status quo with this one particular relationship beyond very minimal increments every so often. And it's not like he's incapable of it either, as you can see in the fantastic yet subtle growth of Todoroki and his growing relationship with Deku. It just leads me to believe that Bakugou is a creator's pet that would fit better in a different story.
Okay? It's still shallow criticism.
It's very telling that you're dismissing the consequences as "nothing but hurt feelings", bringing up the middle school thing, interpreted the most recent chapter as "bullying pieces of shit", and thought the poll influenced the chapter. That all points to you wanting Bakugou to just be beaten up rather than interpreted as a complicated character with both admirable and terrible traits, who's slowly growing up out of those terrible traits.
I wasn't totally serious there. Horikoshi would likely always go in this direction regardless of how popular Bakugou is.
That being said, if you know how WSJ works, you would know (with a few exceptions like Oda), these works are not entirely in control of the authors and character popularity does absolutely play a factor in that. Off the top of my head, character popularity in Jojo and Medaka Box affected the plot. I doubt Bakugou's popularity contributed because it was always going in this direction, but you never know if it really did or will in the future.
As for the rest of what you're saying, the "bullying piece of shit" thing was, as Flowers said, a sort of normalizing of his behavior. With All Might propping him up and acknowledging he and Deku would help each other grow is just really gross to me when he shows no remorse nor any inclination to cool down even further in this particular scene.
And yeah, I won't lie, I'd love to see Bakugou beaten up. By being a dick and just overall more over the top than anyone else in the series, he comes off as a hate sink character, created so the audience would get satisfaction out of his pain. But the story didn't go that way, so it just comes off as incredibly jarring.
And I'd really wish you stopped it with this "shallow" business, I feel I've explained my position well enough without it being dismissed so off-handedly even if you disagree with it.
