I get overlooked by the guys taller than me

The sperm-seekers whose demand has produced this height restriction aren't giggly teenagers or desperate housewives addicted to Harlequin romances. They are strong, autonomous, educated, middle class, not-so-young women of ambition with support systems and resources sufficient to the logistical demands of child-rearing.

Whether childless because of sexual orientation, a ticking biological clock aligned with bad luck in the marriage market, or principled misandry, they view their future child's fatherlessness with sanguine confidence and a clear conscience.

Amongst such committed egalitarians in all other gender-related matters, then, logic would suggest a willingness to accept height parity, or at least diversity. So why are these father-cleansing feminists choosing to "mate" with a stereotypically patriarchal symbol of physical dominance?

Because deep inside, they aren't buying the utopian theories they've superficially endorsed. Freed from the hassle of meeting Mr. Right, and at liberty to conjure up Mr. Right DNA, even women mate-free by choice want to perpetuate via their future child's hologram sire the same symbols of male strength and protectiveness women have prized since time immemorial. Their decision to " disappear" their child's father says manliness isn't important; their atavistically-driven entries on the sperm bank checklist say it is.
