At this point the desperate denial of this inevitable confrontation is nothing but funny.
Can you even imagine how insipid the dialogue a confrontation with the #1 substitute that some people try to push would be?
Akainu: "Finally we meet again...er, I mean for the 1st time son of 
Dragon some insignificant person I don't care about.
Your evil 
father ...er, mentor has flaunted justice and now you stand here as the ultimate insult of all, the 
Pirate King chief of staff of the Revolutionary Army. 
Remember how I told you scum like 
pirates revolutionaries do not deserve to live in happiness? Remember how I chased you down and nearly had you if not for your 
crewmate...er, person that you may know Jimbe, and those blasted Whitebeard Pirates who 
protected you ...I mean who you barely know. The 
scar on your chest...I mean your bare chest is testament to that!
You may have won the war for the throne with the help of the scholar I missed at Ohara who is now part of your 
crew ...I mean an acquaintance, but today I end the wishes of Roger & Whitebeard by killing you whom they have spawned, Monkey D 
Luffy Sabo! I will end the 
blood unrelated associate of the World's Greatest Criminal just as I killed the son of the Pirate King!
That fool Ace will have 
saved you (nevermind you weren't there) for nothing. His sacrifice shall be made meaningless with your death!"
Yeah, brilliant!
