According to Redon, what?
We already have scans. We don't need to see how any fan- just like us, interprets things. But ofc he said it after that attack- but how's that relevant?
I never said he didn't say it after the punch. I'm saying punching in itself is irrelevant to what makes a swordsman or not. Zoro punches and kicks all the time- someone even quoted your dumbass with a scan of Zoro kicking someone. What excludes King as a swordsman is his weird, quirky way of fighting, his weird sword, his DF, and his fire powers. A fuck-ton of things that swordsman don't have.
Meanwhile Shanks is pretty much all swords- only uses swords in every decent fight or clash, had duels with Mihawk, and is outright stated to be his rival. That's most swordsman you can get outside of those who are specifically stated to be one.
Imagine being so stupid you straight up go "If you punch or kick, you're not a swordsman. Proved by King"
