Is it me, or did Lawrence O'Donnell just act like a really big poop?

[Demoiselle]

He was busy telling a young woman (sorry, I'm too angry to remember her name, but I know she represented a women's group) that there wouldn't be ANY money left for her in the Social Security treasury when she and her generation reached retirement. She was trying to make the point that we had thirty years to make changes, that there was plenty of money in S.S. now, and that all the hype about "bankruptcy" was just that, hype. He grinned and kept talking over her, I was surprised he didn't call her "Young Lady" and shake his finger at her. I want him to turn in his Democratic registration card.
He was more respectful of the young man who came on next, who was essentially making the same reasonable points as the young woman.
Sexist (!?)
Feel free to talk me down if you think I've overstated it.
