Ofc you don't care, you can't refute anything and are comparing things totally different with zero correlation.
An ignorant who only knows to talk shit basically. You have no lvl for discussions.
Kaido's might have the same weakness as BM with his hardness. So in that case, that wouldn't be a impressive feat. Rear Admirals could stab WB because he has no natural hard skin too and Kinemon is stronger than a Rear Admiral.
And besides, Kinemon put his all in that stab. If you remember the definition of Haki, is this one:
"Haki" is a power that lies dormant in all the world's creatures... "Presence", "fighting spirit" and "intimidation"... It is not different from the things that humans can naturally sense such as these... 'The act of not doubting'. That is strength!"
Kinemon's fightning spirit/emotions/whatever was at his peak, he have before him the monster who killed the most respected man in his life.
