As for Stan Lee, he did "nuke the commies back to the stone age"-style propaganda, along with heavy support of the military-industrial complex, racist distortions of Asians, embedded Galactus' social-Darwinian might makes right to serial-genocidal degrees conceptual basis into Marvel Comics lore, which irreversibly enormously corrupted it, said that there is nothing wrong with Doctor Doom wanting to assume tyrannical leadership of the world, systematically took virtually all public credit from his collaborators, and heavily crafted a setting calculated to breed addiction rather than enjoyment in children through completely incoherent storytelling without a beginning, middle, and end.
However, I think that he also did good things for representation of African-Americans and women, and working against racism elsewhere as well.
Oda on the other hand has heavily promoted a reconnection to all of our most humane and positive qualities, such as freedom, joy, friendship, kindness, empathy, hope, love, tolerance, and bravery in opposition against extreme cruelty, lies, and tyranny. Why should I condemn him in any way for dedicating his life to helping humanity through genuinely positive inspiration?
