I'm looking for one of you to give me a why that's so personal, I believe that if I don't come back from that training today with a good thing I learned, it'll matter to you. What kind of why could you give me? Yes. My daughter might join the Army in 10 years. Not bad. It's a little problematic. And some people go, what do you mean? If I say I'm a dad or I'm a mom, What's problematic about that? It implies who only matters. Family. It only matters if my family gets hurt, then I'm going to do something. I'm not going to intervene just because a person's been harmed. Politicians do this all the time. As a father, I— they get in front of the podium. As a father, I'm outraged when I see this happen. Shouldn't you have said as a human being? So if you weren't a father, this crime would have been okay? Right? That's messed up.
