That is not what she says. I don’t know enough about the science to know whether I agree with her or not, but at least engage with what she’s actually saying (that pre-surgery and years of hormone treatment, she would have had an advantage):
”My whole philosophy behind all of this is I don’t believe trans people should be banned from sports, but I do believe there needs to be guidelines in effect," Davidson said. "Going back even four years ago or even before I had surgery, I definitely had an advantage. I would 100% agree with that.
"But the difference is now that years have gone on, three years after surgery, my physical capabilities now compared to back then are night and day. So again, honestly, I 100% agree that men do have advantages. Say you get a trans person on hormones for a year or no surgery nothing… of course, for the most part, yeah they’re gonna have an advantage."
