Really? One tennis match decided of all that? First things first: The notion that women's equality rests upon women being just as physically powerful as men is both wrong and doomed. It's wrong because women do not merit equal treatment under the law because they have the identical abilities to men. Equality under the law is a matter of legal and moral standing -- not equality of condition.
It's doomed because it's crazy to suggest that women and men are equals in physical strength. That we still argue about these things is more worrying evidence of resistance to science than skepticism about global warming will ever be. Though you can lose the presidency of Harvard for saying it, there are differences between the sexes. Among the least interesting but undeniable is the differential in upper body strength.
So a 29-year-old, five-time Wimbledon female champion, Billie Jean King, was to play a 55-year-old former Wimbledon male champion, Bobby Riggs, and this was supposed to prove that women were in some cosmic sense just as "good" as men or maybe better?
Why was there no match-up, ever, as far as I know, between male and female tennis players of the same age? Who wants to place bets on a contest between Rafael Nadal and Serena Williams, the winners of this year's U.S. Open? No takers? Not surprising. The New York Times analyzed serve speeds at the 2012 U.S. Open and found that Serena Williams had a serve speed of 125 mph (the fastest among women players). Sixty-nine of the 94 men players served faster than Williams. Only five of 82 women players hit a serve at 120 mph, whereas only 5 of 94 men failed to achieve that speed.
With speed come aces. Only 20 women were able to get 10 aces in the match, compared with 67 men (though men play more sets).
The point is, the ridiculous circus show of Billie Jean King and Bobby Riggs didn't even change tennis -- far less America. Did men and women start playing one another after that? Of course not.
