Maybe I just read too much into things BUT here's my rant.
You CAN critique or dislike a character bc of their actions. It's totally normal and can be how we relate stories to real life. But that does not make them a poorly written character. Obviously, it depends on how their actions are being portrayed in the author's eyes. But it is unrealistic to expect characters to be absolutely perfect and gracious (especially female characters and queer characters and minorities). Like we say we want complex characters but we can't handle a young girl absolutely failing at her personal life and relationships (I'm low-key talking about the belly haters lol). It's okay for the main character to make the wrong choice or to have some room to grow. It's what makes them relatable even if it's a bit cringe. Like I get second hand embarrassment sometimes with things, mainly bc I've had that same level of immaturity and poor execution. But it also feels refreshing to see a character that has the room to be embarrassing. I don't really want a Mary Sue character that already knows how to navigate smoothly through everything or a passive character that just lets the story happen to them. That being said, a character that is imperfect can simultaneously have positive traits! They can be socially likable or creative or brave while also being cowardly, and awkward, and small minded. So if we really do want realism, or to be able to see our flawed selves in a character, then it's important to accept characters that haven't figured all of their shit out. Otherwise, where's the growth? We don't have to like every single one of their actions but it's good to get to know the character in order to understand their actions however silly or unwise they might be sometimes.
