When it comes to groups or categories in one piece, why is their ever only one female compared to the men? For example, Roger and Whitebeard are said to be on the same level as pirates, same goes for big mom. Their are two men, but only one female? This goes for the others like the warlords, were their all said to be on same levels and titles but most are men while their is only Boa? Shouldn’t their be at least one group with two females on the same level of title and strength, like the men have? And even though their are some groups with more than one female, usually only one is superior to the rest.
