Looking into the thought of why girls should act and behave a certain way. It seems like it is an ideal that was sold in the 1950s by men. So it doesn't really say anything about their true nature.
Now the question is why do men want girls to act in that manner. The hypothesis would be that it has some kind biological roots. That men need to feel like they are the protectors of weak and innocent.
Assuming a fraction of this is true, then I can understand the #feminism movement to ridicule the #propaganda apposed onto womenkind to suppress their nature.
@SeekingBlood do agree that society is the biggest factor. Though from what I see, men have the majority say in what it should be.
Let’s say we take the example that women should be pretty or aesthetically pleasing. This seems like a marketing gimmick.
Or the idea that women don’t fart, but rather shoot rainbows and always smell good.
I can understand that the majority is cultural or societal standards, though some of it has a biological component.
