Shanks fans way of arguing is dumb
They should accept that Shanks is swordsman
Anyone who uses swords is swordsman
Mihawk will defeat anyone in sword duel
If Whitebeard or Kaido start using sword, they will lose against Mihawk in sword dual
Doesn't mean they are weaker than Mihawk. They will just lose in
SWORD DUAL but will win the battle.
Swordsmanship is just one of the many ways Shanks can fight.
