Yeah I don't disagree.
If anything people should be acknowledging that they underestimated King and not scale down Zoro lol. But you see the agenda pushers twist narratives.
I think people have been overestimating Zoro a little bit because he really hasn't fought anyone terrifyingly strong. He had a lot of hype from fighting people like Monet and Pica, and Killer, characters whom he annihilated, and he did very well against Kaido, but that was in small bursts.
Zoro has always had incredibly impressive special attack techniques, but even fighters weaker than him like Killer were still giving him a hard time in close quarters.(even though, again, he was significantly stronger than Killer). Given that, its unsurprising to see that opponents who are significantly above the caliber that he could crush fairly easily are giving him a lot more difficulty.
