It was four years ago, and it wasn't on a talk show. National correspondent Richard Berke (since promoted to Washington editor) bragged, at the Gay and Lesbian Journalists Association's convention, that three-quarters of the honchos at meetings (i.e., much more than just the editorial board) where it is decided what will go into the next day's paper, are gay. The other day, pc media writer Eric Alterman claimed that no one on the Times editorial board is gay, but I'm not sure if you could trust Alterman to give you the correct time of day.
You're right that it was Richard Berke, and if it was 4 years ago, well, time flies. I thought, though, that I remembered Berke discussing it on some NPR-type news-in-review weekly panel show, and I thought I remembered him saying that the group that "decided the news" (you're correct about that, too) was (paraphrasing) 100% gay.
And Berke, too, is obviously gay (he wasn't hiding it, although he didn't state it explicitly) -- I remembered 'observing' that as I saw him make the statement.
