Women and men judge with completely different standards and expectations.
Women rate each other the same way they rate men: resourcefulness. How much money, how much education, how high a social status.
Ethnicity plays a part in that too. They all say they're not racist, but Asians and niggers are down the drain every time, even among Asians and niggers.
Men look at different things. They do risk assessments. Are women loyal? No. How unloyal can they be? You can rank that, and the least disloyal women are, stereotypically, East Asians. Southeast Asians are infamously disloyal, but this one looks higher up the map.

>aren't black women famously trad?
They monkeybranch up to the best white guy while clamouring for more feminist/communist bullshit, and when they land white cock they're trad all of a sudden. It's funny how that works.

The point being, women think men rate women the same way they rate women.
We don't.

Any deviation puts your lower down, even if you're loaded with daddy's multi-million inheritance.
