regardless of how you feeling about transgenders there is only two choices here.
Either biological men should not be allowed to play in womens sports.
or
There shouldn’t be any womens only sports and all sports should be co-ed.
those are the only two choices, there is NO OTHER CHOICE.
You can’t defend the need for women to have separate sports and then argue that biological men should be able to compete in them. Because the whole reason women have separate sports is because of the known advantage men have over women.
Give her a break-Hypatia is right. You folks are into getting your buttons pushed.
