I thought it’s been established that you can only “win” when you’re on the island and laughing like Roger did, at minimum
That is not really winning, Roger left something undone, something unrelated to The One Piece itself because Roger brought it up before seeing what the Poneglyphs say.
Remember the series of events. (I am Labeling them from the point of Roger's Death)
14 Years before Death : Roger and the crew find the end of the Log Pose Path and either guess that there is another Island because the Log Pose is going nuts or Lodestar has an explicit clue in plain language.
13 Years before Death : Roger and Rocks duke it out at God Valley, I put this here because Non-0 chance of Rocks telling Roger something.
3 Years before Death : Roger discovers he has CancerAids, decides to make one final attempt at getting to the very last island.
2 Years before Death : Roger meets Oden, and despite knowing he is dying makes his declaration about "Doing X" which requires for him to arrive at the last Island and become the Greatest Pirate Crew (He does not say King of the Pirates, that is a Title given to him by the World Government.)
1 Years before Death : Roger finds The Final Island, Then disbands the Roger Pirates indicating (as I showed before) that the not yet conceived Ace was to be the one to carry on his Legacy, which means that he dropped whatever his original plan was once finding the last Island.
he racial animus against the Fishmem is something I never understood in One Piece.
The World was sinking when The Celestial Dragons got put in charge.
Who doesn't give a shit about the entire world being an Ocean? The Racism wasn't about Supremacy..it was Isolating the one group who is not harmed by The Oceans Rising and who could salvage artifacts from the past world.
Honestly.
I have no motherfucking clue, I am more willing to make a guess about what is on Laugh Tale than I am to say what similar goal that Gol and Luffy might have, especially given that Roger either did it so he disbanded the Roger pirates..or did not achieve it because the History of the world was so important that spending the last year of his life pounding Portgas's pussy until she was preggo and setting up the great age of Pirates trumped his personal feelings.
