Justice [Sonia]Sotomayor said, "Let's talk - you want to talk about the tax power."And I got like a 10-minute run on the tax power. And, boy, was I glad I did because I was able to get across this idea that, yes, this is a narrower ground on which you can affirm it. And I think everybody agrees. I think even the dissenting justices ultimately in the case agreed that, if Congress had expressly called it a tax, it would be indisputably constitutional.

There was this point about, you know, the basic point there as well - this statute treats some parts of the country different from others, and what's the justification for that? Well, you know, I had eight million things to say about that, but he put it in such a sharp, excruciating way that it was just very hard to handle it effectively.

Watch what happens on Twitter. One thing leads to another very quickly. And in an ironic sense, even though it's such a democratic form of communication, there's a funny way in which it leads to a hardening of a conventional wisdom much more quickly than might happen if you were reflecting on it a little more.

I did think Justice [Antony] Kennedy's opinion on Lawrence was critical to that because it really, what Lawrence in one sense was, of course, about consensual sex being something that the government can't regulate. But really in a more fundamental sense, what it was saying, "Look. Gay people are normal people, and they get to live normal lives. They're not criminals by virtue of the fact of being gay."

What we once thought of as necessary and proper reasons for ostracizing and marginalizing gay people, we now understand do not justify that kind of oppression.

If people can live openly and be equal, then you have to have a pretty strong reason to say they can't get married.

Gay and lesbian people are equal. They deserve equal protection of the laws, and they deserve it now.
