...should I dignify that with a response?
You know what? I will.
You see, my fellow anime enthusiast, that shouldn't matter. Why, you ask? Well, its simple, really. Even when the Bijuu were sealed deep inside Kaguya, all bond together into one creature, Naruto could still use all of their powers individually with no issue at all. Therefore, the Bijuu being trapped into the Chibaku Tensei shouldn't really make a difference on Naruto's ability to use their power.
Moral of the story: Double check your facts before you go around calling out people's sh*t. Or else you end up looking, not only like a complete douchebag, but also like an idiot.
