Correct Move By IOC

I have long said that Transgender women athletes should be banned from female events due to the unfair advantage they have and finally the International Olympoic Committee and caught up and said that they face exclusion from future Olympics to protect 'fairness and safety'.
Kirsty Coventry, the president of the IOC, said the decision had been taken because: 'It would not be fair for biological males to compete in the female category' and then made the pointed assertion that the decision was made by the the first female Head of the IOC.
Coventry, a seven-time Olympic swimming medalist, explained that now  all athletes wanting to compete in the female category at the Olympics will have to undergo a one-off SRY (sex determining region Y gene) screening to detect their biological sex  
As the IOC have longed tried toi halt illegal use of drugs wto gain even a small advantage, it is shameful that it has taken this long when the science shows that there is a 12% male performance advantage in most running and swimming events, a 20+ per cent male performance advantage in most throwing and jumping events and 100% in events that involve explosive power such as lifting and punching sports.
There have been some who are disappointed with the charity Dsdfamilies saying that while they understand fairness in competition is important, they are concerned that: 'Proposed processes do not always demonstrate the level of understanding, dignity and respect that this issue requires' which i am not certain what their point is but it is a victory for women who now can be assured that they competing on a level playing field.
The best argument i have heard against athletes transitioning and competing in the sport of their new gender is that this is only a problem with males to females, you don't hear of females transitioning to males and competing and that speaks volumes.
