This is part of the problem, the reporting on this stuff tends to be sensitive so they'll be subtle and refer to her as a woman with high testosterone or something and that leads people to think that rules are very unfair, comparisons with people being tall in basketball etc..
But she's only a woman in the polite gender identity sense, in reality, it seems she's a biological male whose bits didn't develop properly. That someone wants to identify as a woman and was raised as one out of convenience because of a medical condition isn't a good reason to let them compete as one when they're biologically a male.
