When enma drains Zoro's haki it becoms weird according to kaido
Manga proves Enma has Oden's haki. It doesn't matter the vote
Kaido confirmed that enma has oden's haki, we just know the information, there's nothing to believe in
When creating a theory or opinion, you should take into account all the facts in the manga, not just the ones that agree with you.
Kaido says that Zoro has the same Haki as Oden, but then corrects himself and says that he has the same sword. If we take into account everything we know, we can conclude that Kaido was wrong the first time.
That Kaido can recognize Oden's sword is acceptable and explains everything we know because we have already seen a similar case where Zoro is able to recognize a "cursed" sword. Only it seems that Enma's "curse" is activated when she absorbs Haki. That's why Zoro didn't recognize her unlike the Sandai.
Also, Kitetsu (Oda), who is a master blacksmith, creator of a "cursed" sword, says that Enma only absorbs the user's Haki.
