Tennis legend Martina Navratilova appeared to react to comments from Megan Rapinoe over transgender participation in women’s sports as the soccer star gets set to participate in her final World Cup later this month. Rapinoe was asked about transgender athletes in women’s sports in a recent interview with Time magazine. Rapinoe said lawmakers were “trying to legislate away people’s full humanity” and said she would accept a transgender woman replacing a cisgender female on the U.S. national team. As the comments circulated across the internet, Navratilova chimed in with one “Yikes…” The nine-time Wimbledon champion has been an activist for the gay community but has been against transgender women competing against cisgender women in sports. In March, she applauded World Athletics for adopting a policy to exclude transgender female athletes from women’s competitions. She called it a step in the right direction. Rapinoe, on the other hand, was one of 40 professional athletes to co-sign a letter to House lawmakers in April in opposition to the Protection of Girls and Women in Sports Act, arguing that the bill would exclude women and girls from getting mental and physical health benefits.
