I believe this discussion should focus more on equal representation of women and men, girls and boys in the speedsolving community. If the WCA believes that a 50/50 gender split is beneficial for the longterm health of the sport, then a more prominent position should be given to fast female cubers, which may include but is not exclusive to female-only events at prominent competitions such as Nationals and Worlds and female-only records.
Although there is no overt and explicit gender discrimination in the structure of WCA competitions and in speedsolving, the current 90/10 gender split is a huge deterrent for girls thinking about getting into cubing. This amounts to a de facto sexism that is often easily overlooked. The 90/10 split is not unlike the current situation in many science and engineering fields. Participation by girls and women in these fields is seen as vital for longterm economic prosperity as well as gender equality so
there are currently many organized efforts to get girls interested in math and computer science. The point is: if you're a 14 year old girl who just learned how to solve a cube, would you want to get better and attend competitions? Do you have anyone to look up to? We have all watched numerous official solves. How many women do we see in the backgrounds at these competitions? Would a girl feel comfortable in that environment if she were the only girl there?
The creation of female-only events and records is not sexist. Sexism is not only discrimination based on gender
but the attitudes and cultural elements that promote this discrimination along with the institutional power to enact that discrimination. Currently, all five members of the WCA board are men, and there will be a slant (however subconscious) in the board's decision making toward male attitudes. More interest among girls and women in cubing will more likely lead to a future where decisions regarding organized speedsolving can be made with the equal representation of men and women.
As a disclosure, I am a man. I am a teacher at an all-girls school. One question I often get is: why is all-girls education still relevant today when it seems like girls and boys should be taught that both genders are equal? My answer lies in the results. I run an all-girls math team. I teach a very popular computer science course. There are two or three girls at every grade level who are interested in solving a Rubik's cube. There was an informal speedsolving competition that was held at a school assembly last year. This is simply not the case at most co-ed schools.
As a life-long participant in male dominated activities (math team, Magic: the Gathering, computer science), I recognize that it is not enough to stand behind the argument that gender neutrality is the same as gender equality. Action is required. If you believe that the 90/10 gender split is bad for speedsolving, then something should be done. Female-only events and records are two good proposals along these lines and should be considered.
