Let me put it this way. I would much rather read or watch a well written character who just happens to be female than a female character whose appeal almost entirely comes from “Pretty Privilege” and any overused writing tropes in their respective series or genre.
Thank you for taking the time to respond, and I can see where you are coming from. Characters should be written as their own, not merely as "Pretty Privilege".
However, what I was addressing was not on how fictional characters can get away with praise because they're been written by "Pretty Privilege", but rather I was addressing how people/fans argue characters have been getting away with criticism because they claim they have "Pretty Privilege". Let me explain.
When I was in the Three Houses fandom, there was controversy over one of my favourite characters: Ingrid. This is hearsay since I couldn't find significant evidence, but apparently people claimed that Ingrid was racist because she was prejudiced against the Duscur like Dedue, as they killed her fiancé and king (which technically they're right), and they're unhappy with the claim because they say that she had a reason behind and that she grew. However, sometimes one of their main arguments was that people like Felix were worse, as he was even harsher towards Dedue in their Support because he called him a rabid cur. The apparent reason he wasn't called out like she was was that he's attractive.
Now I get it's normal to be upset when your favourite character gets shamed; I've been there. However, even if they're right that others are worse because they're attractive, it oversimplifies things.
Because at the end these supports are very different, starting from the fact that Felix's support has him calling Dedue a rabid cur because he revealed that he will do anything his lord commands him, including killing comrades, women, or children (even if he owes his life). Or that it doesn't make Felix into the only sympathetic character but a flawed jerk, because calling someone a rabid cur is still terrible. There are other factors as well, such as the framing of the support, execution, conclusion, whether the aggressor is called out or the victim stands up for themselves, and so on. Or maybe it's just as bad, but there are so many good things about Felix that might make people forget it exists.
The point is that, based on my experience (or at least in the Houses fandom), fans often use "pretty privilege" to argue why they're not called out, when in reality, there can be many factors, or it simply doesn't resonate with them.
While ‘pretty privilege’ can influence fan perception, it’s rarely the sole reason a character escapes criticism. Reducing complex narrative reactions to attractiveness alone flattens the nuance—and ironically, can reflect the same bias it claims to critique.
