The framing here is really disingenuous. Being concerned about men who "identify" as women being allowed in women's sport is completely reasonable and not mere "resentment". There are real physical differences between men and women, such as bone density, muscle density, lung capacity, heart size, etc that are not undone by hormone therapy or reassignment surgery, and certainly not by self-identification. Navratilova is completely correct, and I'm really shocked that anyone could portray her comments as "transphobic".
