Maybe support the guys who are actively confronting Kaidou right now…
No idea what you are even arguing at this point.
The claim was "only beating the 4 Yonkou will reveal the truth about D".
Everything in the story contradicts that, including Law´s actions.
Roger stole a RP himself, did not face any opposition afterwards beyond the usual, especially since OP world is not as big, and he at least found out the truth without beating BM and Whitebeard.
I am arguing Robin's claim is entirely correct because Roger's situation was wildly different than the current situation. Roger had the gigantic advantage of nobody knowing that the Road Pone glyphs actually mattered.
That is not true this time, the moment somebody makes a move for One Piece they will be a target for every major power in the world. That was how the balance of power has been maintained until well Luffy showed up and dragged Big Mom to Kaido.
