annabeth chase is hated on the most because of the fact that she is the most 'human' out of all the characters.
like out of all the books (that she's present for) annabeth chase is the one who cries the most. she also experiences the most human emotions like jealousy, envy, anger, loss and grief (both for luke, before and after he died). the haters don't like that. they don't like a strong female lead who has emotions that makes her "weak." they want a female lead who throws her emotions away and is submissive does whatever the male lead wants her to do with no ability to think for herself.
the one emotion my girl is ALWAYS being shamed for is jealousy/envy of someone else as if we all haven't at one point in our lives been jealousy of someone. put your selves in her shoes before you start talking abt her.
no one has ever stuck around for her. she genuinely tried so hard to keep everyone that's ever come into her life and none of them have stuck around.
and then she meets percy jackson, a guy who she is NOT supposed to get along with because her mom hates him and she would be expected to hate him because she wants to make her mom proud and acknowledge her. and yet they go on a quest and she realizes that he's not that bad and they become best friends.
fast forward a couple of quests and he's proven to her that he will never leave her side and he isn't like the rest and then one day he shows up with some random mortal girl and then they take over her quest and she lets them, because its the only way to save camp, but that doesn't mean she has to be happy about it.
and then she has one more year with him before she loses him to the great prophecy and she doesn't even see him anymore because he spends all of his time away from camp. and she doesn't want them mad at each other but they just can't seem to get along and suddenly, if feels to her as if he's like everyone else, he found someone better than her and he left.
'oh but why didn't she realize that he had feelings for her earlier?' (dumbest question i've ever heard btw)
my girl only saw him 4-5 weeks out of the year (52 weeks), and that's why she genuinely couldn't tell if he liked her or not. and even if he did, did he like her in a 'i want to date you' way or a summer fling kinda way.
so NO annabeth chase slander will be tolerated.
