can anyone tell me how this space promotes equal opportunity?

It fosters empathy. There are centuries worth of examples of positions of power that were nominally open to men and women, but lo and behold, through some weird coincidence (most certainly not structurally ingrained and unquestioned sexism) only men were selected and hired while women were most certainly equally entitled to apply, BUT just in this particular case, the man was chosen for some reason - once again: not sexism. Coincidentally every single of those cases went that way.

This art installation makes it easier to imagine what it’s like when there’s unfortunately only a limited amount of space in the exhibition that’s nominally open to men and women alike and -due to some strange coincidence- the visitor ticket went to the woman who wanted to visit instead of the man (once again: certainly not due to sexism, but some other absolutely not sexist reason that happened to justify why it turned out in favour of the woman). Just in this particular case. Which coincidentally led to the same result as in every single other case.
