Humanity at its psychological and philosophical core has one long-standing battle of opposites, change, and forces mounted to battle that change. It's never more so apparent than with our relation to women (including the somewhat arbitrary ideal of the female form). Regardless, who's in charge, mostly it's set in stone how women are to be and how to behave.
These set of rules gave birth to the system what is known as ladylike behavior, and a mere half-century ago, stepping out of line was equal to... if you know what happens to Bioshock's protagonist, I need not elaborate. Mastering this system is like riding the Big Kahuna, so it's naturally intoxicating to feel superior in contrast with other women who refuse to. Opposition to self-liberation from that comes from the obvious source, the need for power as a tool of self-affirmation.
When it's being talked about how important self-worth is, it's mostly meant the presumed value within this system. Thus, for many, who derive pleasure from the physical form of female fights, it's perplexing why anyone would be contempt utterly destroying someone without laying a finger on them. Obviously, identifying with the madonna depiction spars the victoress the embarrassment of needing to explain her victory. Beyond that, it gets the target off of her back from letches.
The one mystery that remains for me is, that, in a lot of cases with prisoners of conscience (like Myanmar's president for decades) the point of contention is if captivity is an illusion or not. Turn it around, and from the perspective of an agile woman, it could very well be the illusion of captors, not lack of freedom itself.
