Same-sex marriage was the topic on the Dr. Phil show Friday.

A heated debate took place between San Francisco, Calif., Mayor Gavin Newsome and Maggie Gallagher, the president of the National Organization for Marriage.

The discussion eventually evolved into two shows on the subject.

One question both sides talked about in depth -- whether it's discrimination to ban gay marriage.

"Isn't it possible to be equal but different?," asked Dr. Phil McGraw, the show's host.

"Of course not. Brown v. Board of Education, 1954, the notion that separate is now somehow equal? That's anathema to what America has always stood for," Newsome explained.

"It's not discrimination to treat different things differently, Gallagher responded.

"The difference between bans on interracial marriage were about keeping two races separate so that one race could oppress the other and that was wrong. Marriage is about bringing together the two great halves of humanity, in part so that children can know and be loved by their own mother and father and that's good," she continued.
