You keep using Khabib as a crutch to justify why Islam should be considered dominant over Charles while disregarding the level Charles is at, but I have a better explanation. Oliviera is better than anyone Khabib EVER faced. I seriously need to bookmark this.
More likely, it is that you don't want to believe it as it is selective memory at its best. Khabib was never an underdog in any of his fights on Tapology. Go have a look. He was favorite against Gaethje, Poirier, Conor and just about everyone else. I am sure you would not see that as casuals voting in favor of Khabib. However, because you are such a big fam of Khabib/Islam, you are dismissive when you see the same fans such overwhelmingly voting in favor of Charles because he is much better than anyone Khabib ever fought. There is no one Khabib fought who could pose a good challenge to Oliviera as the common opponents being finished more easily by Charles shows.
