there was an arc about fishmen being discriminated against in one piece and they think fishmen were an allegory for black people. SO because of that they think we should accept their black washing and black supremacy

Its dumb that they compared themselves to fishmen but even with that allegory, there was also a message that the fishmen supremacists were also shit , and that fishmen should not strive for revenge, but should strive for peace . the wokes probably missed that part though of course
