Much of his shit is complete falsification at worst, or embellishments at best. For the longest time, he was pretty much the only western source of information, and his superiors didn't care to verify if any of his shit was accurate. And this is his extrapolation from just one site.
Namely, we have no idea how many of the warriors were female. We know SOME women fought, others were support, or comfort ladies, but to claim that every battle was 50% women is bullshit. Nevertheless, this will give justification for worthless woke vidya developers to shove niggers and women into everything samurai.
