Naruto told everyone that he was the son of the 4th Hokage? Seriously... only Itachi (deceased), Kakashi, Jiraiya (deceased), Tsunade (probably and maybe deceased), Obito, 3rd Hokage (deceased) and Orochimaru (probably... since he knew everything going on in the leaf) know of Naruto's true lineage.
Naruto went through so much ish as a kid, just because he had a demon inside of him. Do you think he would have been treated with a lot more respect if they knew he was the son of the 4th? How do you think the village would feel know if they knew he was the 4th's son?
