P4p rankings are a way to determine who would win if the relative fighters were the same size. P4p takes weight out of the equation, not gender.
Saying that Jedi is p4p better than DJ is saying that if Jedi was a natural 125er, with the corresponding proportionate size, strength, punching power etc, then she would defeat DJ. That is ridiculous. She would still be a very skilled 125 pound woman fighting a very skilled 125 pound man. DJ would win easily.
You just don't get it. At one time 135er Rousey was ranked high in the p4p rankings but she would not have beaten anyone in the men's 135 division. That was a ridiculous ranking. When discussing fighters who are in the same weight class there is no "p4p" because the weight is already equal. That is why it does not make sense to rank men and women on the same p4p list. The women deserve their own list.
Jedi is clearly the #1 p4p female fighter in the world IMO. Why do you feel the need to compare her to men when men have such an obvious physical advantage due to simple biology?
And I do not understand why you think that it is sexist to state that men have a huge physical advantage over women in MMA or most athletics for that matter. Why exactly do you think there are separate divisions for the men and women? In the Olympics men and women compete in many of the same events, only separately. Look at the results of men and women who compete in the same events (i.e. track, swimming, power lifting etc.) and tell me who has the better scores.
Are you really not getting this?
