Males actually tend to have better fine motor skills, spatial intelligence (ability to visualize and see things in 3-Dimensional space), and reaction speeds than women. This is probably having to do with evolutionary adaptations that led men to do more of the grunt work while women focused more on child-bearing and other related tasks. I'd say these along with other social factors (stigma, etc.) are the reasons why men dominate a lot of gaming venues, particularly FPS games. The thing is, women are still allowed to play in these big tournaments, but more often than not, they cannot play at the same level. And yes, perhaps the best EU female team can beat an all-male asian team, but since tournaments are usually done based on regional qualifiers, the female team has to fight for the spots. It's still equality, meaning equal opportunity.
I think if they really want equality and to remove the "male vs female" types of teams, organizations should drop female-only competitions. This makes it more of a "coed" type environment and it opens up people's mentality towards mixing genders or having female players play in large tournaments. However, I personally predict that it will still be stratified because of more biological barriers that will be hard to overcome, save for some exceptions.
