Martina Navratilova and Rennae Stubbs hit out at Caitlyn Jenner as trans athlete debate continues

After taking issue with Lance Armstrong who is a known sporting cheat hosting Caitlyn Jenner on the Forward to discuss the inclusion of transgender athletes in sports, it started a further debate.

Navratilova raised concerns as she has throughout about a biological male athlete conversing with other 'natal males' about this issue and believed it was slightly hypocritical.

"A natal male who cheated in sports going to speak to a natal male to talk about other natal males competing in natal female sports. Got it. I am sure Lance will fix it," Navratilova tweeted.

Jenner did not take kindly to the criticism and questioned Navratilova's criticism of the Grand Old Party (GOP).

"Does your bitterness, @Martina towards Republican lawmakers, candidates etc. (and seemingly the world) actually passing legislation protecting women’s sports, (which you say you care so much about) make any sense at all?" Jenner tweeted.

But Navratilova was unwilling to engage after in her eyes being called 'bitter' and an 'attention seeker'.

"Well Caitlyn- seems like there is no point discussing this with you if in fact it is you who are personally accusing me of things- being bitter and an attention seeker. Sounds more like Sophia to me, but I could be wrong. Thank you," Martina Navratilova responded.

She ended the conversation from there after Jenner screenshotted instances of her showing her support for the Democratic Party. "Caitlyn is doing a lot of research... I am so done with this convo," she commented.

But Rennae Stubbs, former coach of Serena Williams also came to the aid of Navratilova and defended her.

"Martina’s political stance has nothing to do with this issue & we KNOW the GOP are the most divisive bigoted TRANSPHOBIC HOMOPHOBIC group of law makers in government. This is about fairness & in MY opinion we should have empathy for EVERYONE involved, do better!!" Stubbs tweeted.
