The skin color of black people is mainly due to a higher concentration of melanin. Melanin helps protect the skin from the sun's harmful rays and is a natural adaptation.
The reason black people have black skin is complex. It involves evolution and genetics. Melanin, which gives color to the skin, is produced in greater amounts in black people. This provides better protection against UV radiation, which was important for ancestors living in sunny regions.
Well, it could be that Naruto's own chakra nature evolves in an extreme way. His Uzumaki bloodline might have some hidden potential that, when combined with his experiences and growth as a ninja, mutates into the ability to control black holes. For example, his chakra, which is already very powerful, could reach a new level where it can warp space to form black holes.
There are fanfictions where Naruto uses the black fire after making a pact with a powerful entity. This entity could have granted him the ability to use the black fire. He may use it in a strategic way during battles, like surrounding his opponents with walls of black fire to trap them.
It's not always appropriate. White people might unconsciously bring their own biases and perspectives that could distort the black stories. Black people have their own unique voices and lived experiences, and they should be the primary narrators of their own stories most of the time. However, if white people collaborate closely with the black community and are given the trust to tell the story, it could potentially work.
This kind of statement is inappropriate and could be considered discriminatory. Stories should be inclusive and represent diverse perspectives, not based on race.
The views can be diverse. Some might appreciate the diversity and creativity in American fiction, while others might criticize it for not representing their experiences accurately. It really depends on individual perspectives and backgrounds.
