Captain Obvious draws the obvious parallel between masculinizing women and a culture’s operative sexual market.

R-Selection necessarily MASCULINIZES women, because under R-Selection, women have to FIGHT their way into an Alpha’s harem.

You could pretty much state it as a foundational premise of Evopsych that you have “Femininity if and only if K-Selection” [i.e. monogamy].

r-selection is the term to describe a sexual market dominated by polygyny, high fertility, lower paternal certainty (and thus lower paternal investment), and usually the sexual or marital disenfranchisement of beta males. Africa is a prime example.

K-selection is the opposite: a term to describe a sexual market dominated by monogamy, lower fertility, higher paternal certainty (and thus higher paternal investment), and usually the sexual or marital enfranchisement of beta males. Northern Europe is a prime example.

C.O. is right that masculinized women — in appearance and personality — are a feature of r-selected societies, because women fight for a few alpha men, toil for their bread, and generally put less effort into behaving or looking womanly because their men are pump and dumpers who won’t stick around for the duration and are just looking for an ass to hump.

In contrast, the men of K-selected societies are romantically inclined to long term monogamy, and seek women with very feminine attributes. If a man is in it for the long haul, he’ll want a woman who herself brings a lot to the bargaining table, and her number one asset is her loveliness and femininity.

[You just stated that it's the other system where women have to work, and you're very eager to talk about how poorly women age ("The Wall"), what the fuck are they bringing to the bargaining table in your K-selection?]

If a nation’s women are masculinizing, that is a portent of civilizational collapse, because r-selected societies are backward, violent societies filled with bitter beta males and bastard children. The masculinizing women are biologically responding and adapting to a change in sexual market norms and functioning, that requires of women a willingness to compete more forcefully with other women for the honor to be part of an alpha’s de jure or de facto, concomitant or serial, concubinage. As a culture’s women become more or less masculine, that culture is likewise becoming more or less r-selected.

[There's a lot you could say about that last one, but Cosmo being masculinizing is a new one.]

These and more are the cultural hallmarks of masculinizing women. The West is becoming Africa (minus the cannibalism, but give it time).
