@Ao:
I'm not personally denouncing anyone.
Fact is Luffy never gave Zoro a position, thus he has NO POSITION. There was a whole thread dedicated to this realization by the fanbase here awhile ago. Altho fans tend to list him as the firstmate Luffy never says or even gives any indication that Zoro has a ranking crewmember any higher than simply "member of the team".Zoro seems to be second in command,but he's defintely not the first mate despite the "myth" that's been going around for a long time. That's a big difference from Usopp who was literally named the crew's Sniper by Luffy or Sanji who was named the chef. Zoro was never given such a position. Hell, he's never even been officially names the strawhat's swordsman which is why Brooke is allowed to wield a sword as well.
4kids Luffy refers to Zoro as "First Mate" on a DVD I have of 4kids Promotions.
