I've seen some says that because the databook says that termari can blow away the universe (obviously a hyperbole) that it is trash. Is this what people really believe, or are they just joking?
There is this type of hype that many people (the fanatics) really love also in the manga.
A lot of humans like to "believe" in something they can't explain.
You can't have a debate with a guy who "believes" in something , he is just a fanatic that can't reason , you , as a smart guy , should recognize those people , and pass your way.
Never try to debate with a fanatic.
General exemples: Hiruzen hype , Itachi hype , Yata mirror hype...And now Temari hype...
It's like having a debate on "the indestructible wall VS the weapon that destroys everything".
