Wow, going after superheroes and fairly tales really says something. If you want to show real problems to broader society and be considered serious, choose a better strategy than pure propaganda.
If one would take a closer look, almost all fairly-tales, fantasy stories, comic books, tales, old songs, folk art, etc. have similar (broadly speaking) themes and few story lines. Stories are tied to local traditions, history beliefs and represent general thinking/expression of art at the time. However, there are 2 main points - 1) many of these stories are pure fantasy (unreal) if taken at the face value and 2) no real person would willingly live in one of those stories if you think about it. Point 1) is pretty obvious. As for point 2) - let's just say that stories are simplified and not suitable for normal human being - blood is spilling free, superheroes are actually superlosers (they even have superpowers but still cannot do anything useful), many characters are too stupid/honest/strange, role of regular people is beyond miserable.
Sure, some fairly tells have some hidden agenda or indoctrination. But it is up to a person to understand/learn/decode it.
Now, to claim that fairly-tales/comic books/etc. are suppressing women and should be banned/modified to fit "perfect view" is to work for a propaganda agency which puts dirt on everything it sees as non fit for its agenda. Do we have to burn books again because you do not like some pictures? Where has the freedom of speech (art/expression/...) gone?
Some say cover pictures put too much influence on young kinds/instil "wrong" expectations so it should be removed/banned. I would say it is not a bright idea because it is not that simple, society itself puts expectations/world view in our heads by many means. Also not everyone is the same, so forcing "right expectations/worldview" of a single "right" group to all others is simply not right.
I may not like some newspapers/fairly-tales/books/comic books because of their style, pictures or story line. In fact, pick any work of art/newspaper/etc. - there almost surely will be someone who does not like it because of personal taste, political views, agenda or any other reason. However, I will defend media sources/book publishers from restriction/ban because otherwise we will completely loose all freedom of expression bit by bit.
