Separating people by their ability has nothing to do with their rights: just as there are different competitions for different age ranges in sports, there are also different competitions for different sexes. It does not make too much sense to have separate competitions for different races, as in that case the differences in ability are not entirely clear nor provable, but if they were, it certainly would make sense. It has nothing to do with patting women on the back either: it just depends on weather people want to see women compete or not. If they do, they must provide for a competition where they have a fair chance to win, otherwise it is not a 'sport' competition any longer. Just as you would not expect a child to be willing to compete in an adult competition, you can't expect women to be willing to compete in male competitions.
