most media will be considered problematic by someone and that's ok

every single piece of media will have some sort of controversy, the only way to have no controversy is to be a writer nobody knows about(like me), and with nobody i really mean nobody, because if 500 people know about your fanfiction in a fanficton site or something, some controversy may already appear, don't bellieve me? let me show you some examples(i would cite sources but the post was banned when i did it):

.Paw patrol was critized by certain people for being pro cop propaganda due to having a police dog

.I've seen an article saying hello kitty commodifies asian woman

.I've seen that there is a theory that spongebob promoted homossexuality(wich was considered as negative back then)

.I've seen people complaining that the sonic 3 movie is way more pro system than sonic adventure 2(perhaps is more of a complaint, but it's still something people find to be problematic about the movies)

.Mickey mouse, perhaps being depicted as squeacky clean, can be seen as sexist due to the only main female characters we see in most cartoons(minnie and daisy) are basically carbon copies of male characters made only to be love interests

people may say that these people are finding problems where there aren't any (or searching for hair in eggs as an expression in portuguese says), but i also think this is a reflection of how you cannot please everyone not just on the sense of quality, but also on morality, it is also reflects how humans are flawed beings who can and will write flaws in their stories, some of these examples like the minnie mouse one are clearly sexist.
