What does this prove? It's the same shit as "He's the coolest" The only different here is that a reason was provided.
"He was the coolest"
"He was the cool because he wanted to become hokage"
"As someone who wanted to become hokage, he was nothing but Awesome"
The 'nothing but' there basically states that Obito has always been awesome 'because he wanted to become hokage'. Obito Killed thousands of people and destroyed villages? No big, he wanted to become Hokage when he was 12. Every iteration of Obito is the same person, you can say "Oh, naruto refers to blah blah as masked whatever" but the fact is it doesn't matter what he referred to him as, he was still a mass murderer. If we only include the obito's that "Wanted to be hokage", that's <12 year old obito and the 5 minutes of obito who was revived by narujesus. Even then, those phases of obito barely fit in with the context of what BZ was talking about so stating that naruto's response was directed solely at them implies that naruto went off on a significant tangent with no warning or sign.
