They don't like female characters you have to think about twice or more to understand. I talked about Anthy because she's the literal representation of this treatment so imagine the irony if she was hated too. Which she would surely is

My favorite girl sport manga is sadly not even a Shojo even though it focus really only on female character.

They're hated by both men and women for being "weak"… I keep wondering how people would react to Anthy Himemiya if Utena was released now.

People did hate and wished death on Kakeru Naruse, or called Itsuomi and Hananoi predators. It's just less common but these days, calling ML toxic and predatory happen more.

Shojo heroines are still the most hated kind of female characters there is.
