Well it's the very first time I saw someone say Deadfire is pro feminism.
Of the 4 major factions, one is a council so does not count, 2 are led by women, but don't forget RDC is just a tool of Ruauatai empire and I believe their ranga nui is a man.
If you look at the smaller factions' leadership, I simply don't get how you can reach the conclusion that
Port Maje: let's say 1:1
Tikawara: male
Ashen Maw: the one giving order is male
Junvik: female
Dawnstar: female
Temple of Gaun: female
Temple of Breath: male
Cult of Rymrgand: male
The list can go on and on. I never noticed the game is yelling "women powahhhh" in any way. You also need to remember fantasy games have a long history of making women "not weaker than man" so that the
can play as whatever character we like.
TBH saying PoE, not any other modern RPG, is pro-feminism, tells more about yourself rather than the game. Imagine in a objectively gender-balanced world you find yourself annoyed by the fact that women have jobs.
