I never said anything of that. I only said Madara isn't that durable for OP standards, then you started the whole sword-level campaign. I even explained in my reply to Senti that Madara is among the most durable guys in OP. Again, this is all because you tried to act like a smartass instead of asking me the right questions or at least reading my replies to the guy I was having this discussion with.
You literally agreed with me when I mentioned sword level Madara, if you were joking then make that clear as it isn't through text.
I really don't understand what your point is of repeatedly bringing up Madara flying into a sword if not to downplay his durability, there is no point to it unless you actually believe Madara has regular human levels of durability which given your recent posts you do not.
Again, I never said taking damage means you have no durability. This is another case of you not reading my posts. My only argument in short is, "The stronger the attack it takes to bypass your defense, the stronger your defense." I used this logic to say Kaido, and King, by extension, is more durable than Madara. If you're damaged, then your durability is overpowered, and if you continue fighting after taking damage, then it's a feat of endurance." I also said durability mitigates damage in my previous post in case you think I don't know it.
You just did a very poor job of explaining your point, I'm clearly not the only person to believe that was your intent going by what Sentinel and soheilhazrat said, you were literally suggesting that Madara tanking direct hits from the Biju with nothing but a bit of blood makes it an endurance feat and not a durability one, even though if Madara didn't have at least relative durability to the attacks he would have been reduced to mist or a puddle as that's blatantly how durability works.
And no, Kaido does not have greater durability than Six Path's Madara, again, Madara's eating attacks from at the minimum moon level characters as oppose to Kaido who fights country-continental level characters, their feats of durability aren't even comparable once you understand that fact, just because attacks in One Piece sometimes look more impressive doesn't mean they actually are.
