Ideally, there would be 4 areas of athletic competition: M, F, M-t-F and F-t-M.
That would, perhaps, be the fairest thing that still allows for a recognition of real differences.
Because saying that women and men have real and scientifically verified physiological differences – the use of energy and sustained performance aerobically, density and length of bone, composition of muscle and ratio of of fast-twitch to short-twitch muscle, and differences that unfold during the body’s most important and powerful years of development – is not ‘prejudice’ but rather an acknowledgment of scientific facts and thus, by extension logically, taking those differences into account would make for better sport and better competition.
(This is not an attempt at diversion/digression, but, rather, an honest answer to a posed question; now returning to Presidential Candidates.)
