Bro, get off this boat while there's still time.
Roger, Xebec, and Shanks fire their haki like cannons; that's an infinite difference in cutting techniques that you need to be able to master to call yourself a swordsman.
There's a reason they've never been called swordsmen in the entire history of manga, lmao.
This has to be sick sadomasochism. You know you're wrong, but you're going to continue this retarded argument because it seems like your blessed egos are going to be too bruised, all to be molested in the end when the manga proves you wrong. Weird nerds, I can never fathom how deep into the mud of this argument you can go.
