and I answered with a different, stronger and more veteran character who IS questioning it
Kaido was questioning Luffy's statement from previous chapter
Luffy made a statement at the end of chapter 1000 that he will surpass and become PK
Then the conversation continues with Big Mom questioning Luffy's statement
And then Kaido
in his head head questions Luffy's statement,
if he implies that he is as great as those 5 pirates who surpass Kaido and BM and can become Pirate King
.....
He questions his statement in his mind. Are you like autistic or something? This is toddler manga
Lots of people can fight Kaido, shut up with that nonsense.
BM can fight Kaido, she is not on the list
Mihawk can fight Kaido, he is not on the list
Shiki can fight Kaido, he is not on the list
Garp, Sengoku, Admirals can fight Kaido, they are not on the list
Use your brain and follow CONTEXT.
Context is that they are talking about PIRATE KING tier pirates who are ABOVE Kaido and BM
