I don't usually link to specific posts by Atrios since I figure everyone is reading him anyway, but his post about identity politics is one that I really want to make sure everyone sees. I also recommend what Steve Gilliard says (no permalinks, scroll to "A real live minority viewpoint"). And just to show how "diversity" can manifest itself in ways you wouldn't normally think about, check out King Kaufman on Rush Limbaugh's "official" debut with ESPN's "NFL Countdown".
