Always funny when people bring up Luffy saying ''Akainu'' in a single panel and act like it was a big deal but Luffy in the next panel is chomping meat and forgot all about it
So your evidence is that Luffy gave a fuck about Akainu for all of 2 seconds and then didn't even want to hear anything else about him?
Weak.
Also not to mention this was 10 years ago and Luffy has never even given a single hint that he wanted to go after Akainu and avenge his brother any more than he wanted to go after the celestial dragon he thought killed Sabo.
And if you actually want to use Jinbei's speech, he literally stated that it is
blackbeard who Luffy has the score to settle with NOT akainu. Akainu even in your own example was relegated to the back of the line and Blackbeard was said to be his opponent.
Sabo is Akainu's opponent, and given that Luffy is currently far stronger than Akainu, at most he would be a Blueno fight with no significance.
