Gender is definitionally cultural. A person’s sex is nature, but the bundle of signifiers that denote gender (as well as which categories exist at all) are largely arbitrary and divorced from that, and vary greatly across time and place. Women wearing pants was unheard of a century or so ago, and would 100% be perceived as queer, nowadays it’s completely normal. There were times when dueling was a virtually mandatory rite of passage to being considered a man. There are also historical cultures with more than two genders, and it’s not as if people in those cultures were biologically different from others.
There’s nothing “extraordinary” about this claim.
I brought in the new year playing Fire Emblem: Awakening (which I’ve been obsessed with after finally getting it working on an emulator). I’d been struggling with lunatic mode but I figured out I can just feed Robin because of the XP boost and then use her to carry the team. Changed her to Pegasus Knight and then Dark Flier and now I can just swoop in and one-shot any enemy and she’s over-levelled enough that the enemies won’t prioritize her, and if they do, she dodges everything and has enough HP to survive a bow to the face.
The early levels were very challenging and I had to heavily abuse save states but once I got rolling it’s been a lot smoother. The two cavaliers you start with literally can’t survive a single hit starting out. Since everyone’s so vulnerable, you just have to get one unit good asap to avoid relying on your Jagen.
