It's hard to respond to the topic without sounding like a chauvanist. I'll give it a shot though.
As much as fundamentally sound players are important to team success and should be coveted by coaches and GMs alike, fans are excited by incredible feats - slam dunks, fancy passes, impossible shots - we consider these highlights, and we expect to be entertained as much as we expect a good game of basketball to be played.
Back at the 1998 All-Star game, the first year of 2-Ball and the first year since 1984 that the All-Star Weekend didn't feature the dunk contest, the commentators were all plugging 2-Ball and talking up the problems with the dunk contest, that it didn't showcase true basketball skill, that it was boring. Cheryl Miller confidently announced "Forget the dunk contest, 2-Ball is here to stay!"
So here it is, the year 2003, 2-Ball is gone and the dunk contest is back. This year's contest was one of the best in recent years, and arguably one of the best in history, brief as it was. 2-Ball showed the fundamentals of basketball: passing, shooting, rebounding missed shots. The problem is, that won't translate into a sideshow; you can see all of that in a regular game of basketball.
The dunk contest takes away all of the other elements of basketball, relaxes rules on dribbling violations, and shows a player's creativity and athletic ability. Perhaps it's not a showcase of players who are fundamentally sound, but it's fun to watch.
Even when you put everything else back into the game, and the slam dunk exists as part of the game of basketball instead of its own sideshow, it's still an exciting display. Dunks are extremely rare (to say the least) in the WNBA - as far as I know, Lisa Leslie is the only WNBA player to dunk in a game. With the highlight reels the NBA produces, it's difficult to sell basketball fans on WNBA highlights. Poor form, worshipping flair over fundamentals? Maybe, maybe not, but definitely the way things are.
On a more basic level, it's difficult for men to enjoy or truly appreciate women's sports. The sports-crazed father wants his sports-crazed son to grow up to be the next Jason Kidd, Kobe Bryant or Tim Duncan, not the next Lisa Leslie. Since professional athletes are always going to become role models, boys are going to look to male athletes as role models.
I also pretty much agree with the article. I've never sat through an entire women's hoops game, be it WNBA or Australia's WNBL. Not because I'm sexist, simply because I don't find them as entertaining. I'm a fan of basketball, but one who has been raised on dunks. Dunks have become an icon of the game - in pretty much every non-basketball TV show or movie that makes reference to or features basketball in some way, nearly all of them identify the dunk as a part of basketball.
So I disagree with the notion of sexism playing a major role here - simply, people are free to choose what they like about sports. Most people prefer the style of the men's game, that's all. No chauvanistic feelings, just difference in taste.
