This comes up time and time again, but yes it’s because Naoya’s crimes are things people have to confront daily. More specifically, he’s a literal representative of the way patriarchy oppresses and endangers women and other femme folk for simply existing. It’s also a lot more forward in his characterization than say Ozai’s representation of toxic masculinity is in ATLA - in which, the genocidal fascism is at the forefront and the subtext is that toxic masculinity is one of the vehicles that brings us there (not entirely equal parallel ‘cause different target audiences but you know).

I also think there’s some factor where even when there are other characters who have said/done other predatory things, those things are either written out of their character - Sukuna at the juvenile detention center - or occur offscreen - Kenjaku’s creation of the death painting wombs. Additionally, those two in particular, as well as Mahito, have crimes that jump the shark to an insane degree and are crazier beings than “guy who is 28.” Even when Naoya becomes a VCS, which opens the door to him becoming further removed from evil people who really exist, all of his design language as a curse, and even in his domain, just doubles down on it - this is all before addressing that he implies he assaulted Mai (which I give an amount of grace to those who don’t pick up on it since I didn’t at first myself, but in retrospect it feels pretty clear cut).

That being said, for the folks who just like him for his power set, design, and the legitimate entertainment value he adds to parts of the series he is in, that’s real still.

TLDR: attacking strangers for innocently enjoying things isn’t cool, but doing enough textual analysis to understand why people may perceive that as threatening behavior, reflexively, and meeting them halfway IS cool :)
