You are basically saying: rock golem has no durability feats so Danzo's fuuton cuts through it. I could say the same thing. Danzo's fuuton has never cut through anything of noteworthy durability so rock golem tanks it with ease. And wow. you really did go full retard when you said size difference doesn't denote durability difference. I guess the fact that Gaara's sand shield tanked C3 has nothing to do with the fact that it's massive? My example's not irrelevant. Rock is more durable than sand so chakra infused rock is more durable than chakra infused sand unless the chakra ratio is significantly different right? Not to mention it's bigger and thicker than the sand mother, and Madara needed strong attacks to take ot out both times (V3 Susanoo and large scale mokuton). The fact that such a tiny golem protected them from Deidara's explosion only goes on to suport my point since there's a larger gap between the two different golems than there is between C1/C2 (we don't know which it was and frankly it doesn't matter) and Danzo's fuuton. I suggest you stop beating around the bush and giving BS examples to reach the conclusion you want to reach because Danzo's attacks are not only MUCH SMALLER than the golem, they have a 0% success rate against any Susanoo. So please use this thing called common sense.
-Gaara's sand only stopped C3 because it was imbued with chakra. Db3 confirms this.
-More rock=better durability against brunt force attacks. The momentum can be reduced further and it'll have a more difficult time smashing through it. A penetrative attack would cut through a small rock golem practically the same as it would cut through a large rock golem because its momentum is not the reason it is slicing things. It slices because it is very sharp, ie raikiri doesn't need a quick swing to pierce the same amount it would without a swing.
-Danzo's Futon needs no pure quantifiable feats to be put above Rock golem. He does the same thing he did against Susa o but with/without Baku and the rock golem goes bye bye as there's no reason for him to survive such a penetrative attack. Inb4 the retarded Baku suction is only reason his attack has strength, and without it it'd have been useless and weam argument.
-Stop with your idiotic logic. Rock>sand irl, sure. But this is manga and sand is the absolute defence. It can absorb impact much better then rock irl too, and in this manga sand>>>rock durability wise. Especially when Gaara's hardest sand was capable of cracking Kimimaro's hardest bone by just resisting against it. So this sand<stone argument is absurd.
-lol. So having 0 success rate against Susano makes them weak? I guess Tsunade is also weak because she'd be incapable of destroying v3 Susano too lmao. At the end of the fay, there's no reason to believe his Sand golem can protect against Danzo's penetrative futons. The focus their energy in a single line whereas Deidara's explosion is energy completely dispersed. Golem has tanked nothing of the like.
