Discuss? It's a poorly constructed metaphor. What do each of the parts relate to? Judging by the structure of it, the pill is Pandora's Box, but the pill doesn't contain anything. Pandora released evil from the box, so shouldn't the pill be represented by Pandora in this metaphor? And Pandora's Box didn't give sickness and death freedom, but in fact contained it - the complete opposite. 'ickness and death' correlates for some reason with 'women reproductive' which isn't even a noun phrase. The noun phrase is 'reproductive freedom', which means that sickness and death must represent 'women' and 'reproductive freedom' correlates in the metaphor with 'freedom', which doesn't make sense. And are you saying that reproductive freedom is bad for women, or for the world? Because the evil released from Pandora's Box was explicitly universally bad, which I figure is how you feel about women's reproductive freedom. Which, if that is true, means the metaphor should go 'The pill released women's reproductive freedom to the world, like Pandora released the evils of Pandora's Box.'
The way it is currently written makes no sense, as for a metaphor to work, at least some of it needs to match up directly.
'The Pill' doesn't relate to 'Pandora's Box' but to Pandora.
'women' doesn't relate to 'sickness and death' but to the people of Ancient Greece.
And 'reproductive freedom' doesn't relate to 'freedom' but to 'sickness and death'.
There, I discussed your metaphor. I also disagree with the spirit of it, but the construction was so egregious I couldn't ignore it.
