Well thanks for clarifying your opinion, Eoin.
Of course, we wouldn't literally be "barring" women from Elite Sports events. They'd be allowed to compete if they can reach the same level as the top men.
In some disciplines, they probably wouldn't be able to do that. But that just puts them in the same position as nearly everybody else, who, for whatever reason, is unable to compete with the best.
My parents weren't tennis coaches and couldn't afford to pay for me to have access to tennis courts. This put me at a severe disadvantage compared to Serena Williams. But whereas she's given special dispensation so she can win Wimbledon anyway, I get no help at all. Seems unfair, don't you think?
