I thought I got it - you know give everynoe a chance to participate, but I've just come back from a shambles of a swimming gala where the not so able swimmers were humiliated in public by desperately trying to participate from the back and the able swimmers were not allowed to compete in their strongest strokes. What if the able swimmers fail at everything but swimming and this is their chance to shine in something? I'm prepared to be persuaded but right now I think it is PC gone bonkers.
