Martina Navratilova is not happy with Australian Open tournament director Craig Tiley's comments on letting trans athletes compete in elite women's tennis.Tiley recently stated that Tennis Australia, of which he is the CEO, is pushing the world governing bodies of tennis to maintain inclusive rules for transgender players.Tiley said that Tennis Australia has been speaking with both the International Tennis Federation (ITF) and the Women’s Tennis Association (WTA) to allow transgenders to play at the elite level.“When it comes to professional tennis, we’ve got to be responsive to the international tennis federations. They set the guidelines and the policy on it. But you know, as a sport, we’ve made our position pretty clear … and we are supportive [of transgender inclusion],” Tiley told the Sydney Morning Herald.“We’re trying to influence the decision now. We are an organisation that believes absolutely in inclusivity, in diversity, in equality – so any decision made will need to be aligned with our core values,” he added.Eighteen-time Grand Slam champion Navratilova, who has always been vocal about not allowing trans athletes to compete in women's sports, was understandably unhappy with Tiley's comments.Responding to the news on social media, Navratilova said that it wasn't a good idea as it would take away the spots meant for 'biological women'.“Oh boy. This is not a good idea at all. Trans athletes are included in sports- in the biological category, not in their chosen category. By including trans identified males in females sports, spots for biological females are taken away. I am not ok with that,” she tweeted.Martina Navratilova@Martina@fem_mb @CraigTiley @WTA @ITFTennis @FondOfBeetles Oh boy. This is not a good idea at all.

It’s that simple.Seems to me Craig Tilley doesn’t understand that concept,” she added.Martina Navratilova@MartinaBy including trans identified males in female category, biological females lose a spot.

In November last year, the Canadian Centre for Ethics in Sport (CCES) commissioned a report on the advantages or disadvantages transgender athletes might have when competing alongside women in professional sports.The report stated that there was very little research on the potential advantage of trans female athletes over cisgender women before and after Hormone Replacement Therapy. Navratilova claimed the report could be inaccurate and said that she was tired of women always getting the short end of the stick.Martina Navratilova@MartinaCould be because the report is wrong. The advantages are obvious even with mitigation. Prove there is no advantage and then include, not the other way around. Women get the short straw again and I am sick of it! twitter.com/EthicsInSPORT/…CCES@EthicsInSPORTIn an effort to create a safer space for trans and gender diverse people and people who want to learn from this report, the comments for this post are closed.1427253In an effort to create a safer space for trans and gender diverse people and people who want to learn from this report, the comments for this post are closed.Could be because the report is wrong.

That would be bigotry? What is not cool is not having those spaces… check your male privilege, please.2660219@bgilman66 @triggerpod @andrewdoyle_com @francisjfoster @KonstantinKisin Not cool to be asking for the right of women to have our own spaces?
