Steve - I suppose what I want really is rugby... and sumo wrestling...

Women's rugby is coming along,
but it's a sport where the physical disparity between men and women
may be too much for mixed sex teams to be feasible...???

Though rugby teams do have positions for smaller men...

But if schools and local clubs started boys and playing together in mixed teams
right from the get go,
maybe that would sow the seeds for a next generation that takes it for granted as the norm...???
Team selection based on individual skill and enthusiasm for the sport
rather than gender...
Footballers are all round athletes, and the physical differences betwen men and women
should not be as significant as in other sports like rugby and sumo..
