KIzaru did hit luffy.
Luffy himself said he almost died after he got kicked into 2 barriers.
What did Luffy accomplish ???
He landed a hit on Kizaru who was before that fighting someone else, both got on the ground only difference is Kizaru got up on his own faster and without outside help while Luffy had to be feed by someone in order to continue foghting.
I guess yonkotards have fallen so low that now landing a hit is considered a victory
