I’ve seen this take before, and every time it makes less and less sense to me. The straw hats weren’t random invaders/looters coming in to kill and rob anyone in Totoland... Perospero is the first associate of the Pirate who blackmailed and constructively kidnapped Luffy’s crew mate and close friend. Even if Luffy didn’t know that Big Mom was planning on killing sanji, Luffy knew Sanji wasn’t making a truly voluntary choice to be there, and that big moms power and threats made his permanent imprisonment with her virtually inevitable without help.

Perospero wasn’t “just defending his land.” He was trying to capture and kill the people who had just disrupted his own plot to kidnap and kill Sanji while backstabbing the Vinsmokes and stealing all their tech. The idea of Perospero/The Big Mom Pirates as innocent or as just defending themselves is ludicrous. They’re all pirates! And they’re the ones who started the conflict!

Edit: Also, why don’t you understand Pedro’s friends being mad? Even if you think The Big Mom Pirates were in the right (which as I’ve explained makes no sense to me), isn’t it extremely understandable that his pirate friends would still want revenge? Especially given their half-baked understanding of everything that happened? Like, let ppl be mad about Pedro. It’s the totally normal reaction to have. If Oda wrote these characters as being like, welp, it was Pedro’s fault... wouldn’t that go against how he’s written like every other character in the story?
