The reason I say action yaoi is because we have just like a bunch of dudes smacking one another with phallic objects over and over again. And don't tell me that the keyblade isn't junk metaphor, "keyblade envy" is a real thing in this series and it reflects all the typical signs of that other kind of envy. But it's like aggressive fast paced yaoi so different and foreign from traditional yaoi....like cherub mating in homestuck. Just like darkness is a metaphor for testosterone and masculinity....and again I point to the keyblades our darkness users (Riku, Terra, Xehanort) are especially long. Or look at Ventus his keyblade is tiny like really tiny while his dark half suddenly has a much longer keyblade for no reason.
In fact typing this I change my post KH is 100% things that can be easily taken in the wrong way.
