It's a perception our society has. Our society is in favor of the majority, their men and women must represent the norms of masculinity/femininity. W/o this, it's a loss of power. So due to subliminal signals, the easily manipulated are influenced. They're influenced to reject anything different from the norm and perceive it as undesirable.
Albeit I might be giving you too much credit, your mind maybe far too.....simplistic to even process what I'm explaining.
Any who, you're purposely trying to irritate us Black women, that much is obvious and it's quite childish. You want our attention and since we wouldn't pay attention to you otherwise, decided to put that tiny little brain of yours to work and insult us but not even directly, how pathetic.
Lastly, Black women actually possess more estrogen than other racial groups of women. It's why Black women are more likely to die from breast cancer than White women are, unfortunately.

So that theory is thrown out the window.
I say it's simply your perception, which amounts to nothing really.
