This is probably just a Hey Arnold fandom thing, but everyone seems to hate on Lila because she happens to be who Arnold has a crush on long-term in the series. It’s always bothered me that their hate of this character is rooted in misogyny and the fact that Arnold likes her and not Helga. It’s such a bad reason to hate a character, and it still upholding the societies hold on what they want from us. They want people to hate women characters, and in its self-other women. They pit us together on purpose and thus reinforcing it.
