STEVE DOOCY (CO-HOST): A lot of people are up in arms over this because it is just a fact when you talk physiology men are stronger than women. So even though this woman was born a man, identifies now as a woman, she still has a man's body.

KEITH ABLOW: Well yes, that person does have a man's body. And you know what, Steve? Identity is not necessarily a reality. What a person identifies as, doesn't make it a fact. And I would say, it is my medical opinion, other psychiatrists have different opinions, the folks who identify as a gender other than their own born gender, their maleness or femaleness at birth, they haven't found themselves, they've lost themselves. It isn't true.

DOOCY: What do you mean?

ABLOW: What I mean is that if your DNA says you're female and if your anatomy say you're female, you're female. Your identity may be something different, that of a male, but it's an open question whether that's actually an illness, not something to celebrate. And what we see is that because these identities, which I would say are false identities, because they are being celebrated they are creeping into our culture and they're exploding the truth about many things we value. In other words physiology. It's true, male athletes can often perform much more substantially than female athletes, but this identity, irrational as it can be, explodes our truth as a culture. It changes our bathrooms, where we know for a fact that people with male anatomy should go to the men's room. People with female anatomy, the ladies' room. But these few people who I think have lost their true identity, are breaking up the truth for the rest of us. It's a very big threat to our culture.
