That's not her point, at all. Her point is that the harm done by marginalizing, stigmatizing, and punishing a group of kids who are already threatened and vulnerable is much greater than the harm done by allowing them to participate in sports. Someone's gonna get hurt, either way, and she would argue (and I would agree) that inclusion should be the default and that the degree of cruelty in the response is not merited by the magnitude of the "problem" incurred by including trans girls in sports.
