It was never: "Garp and Roger teamed up to beat Xebec"
It was always for the past 200 chapters: "Garp and Roger teamed up to beat the Rocks Pirates"
Fan Headcannon turned it into Xebec vs Garp and Roger. People have been trying to correct this for ages, but Agenda Piece reigns supreme over One Piece.
We also literally see that Xebec is the one who started the fight with Roger, not vice-verse. Yet the fandom still pushes "Roger fought Rocks to protect CD slaves".. lol.

Come on.
Although yes, obviously Roger Rocks and Garp weren't trying to help the CDs or whatever.
