Maybe you should start learning how to read moron, wtf are you talking about? Some troll posted a pic shows Law as a swordsman, is that mean WGS title makes someone stronger than someone who has Law's skill set?
Yes, because he has stronger haki to be a stronger swordsman than Shanks, so obviously he's a stronger swordsman than all the other swordsmen in that picture. It is not a difficult concept.
"A pic". Do you know that picture was shared by Oda confirming they are, indeed, all swordsmen?
The whole discussion about "who is a swordsman" wouldn't exist if not to slander Mihawk. In what other manga do people question characters being swordsmen even when their main weapon is a sword and they use all of their abilities through it? You're questioning even Shanks, who has literally only used sword techniques in more than 1000 chapters.
"His technique didn't even cut", good thing Zoro's master gave him a lecture about real sword masters having the ability to choose what to cut and what not to cut, that makes Sahnks a real sword master.
