I'm with Hitch on this one:
Until 1978, the so-called Church of Jesus Christ of Latter-day Saints was an officially racist organization. Mitt Romney was an adult in 1978. We need to know how he justified this to himself, and we need to hear his self-criticism, if he should chance to have one.
The awful history of the LDS church's treatment of African-Americans requires an accounting by any leading Mormon, as Romney is, who didn't protest at the time. I blogged a while back about Darron Smith, a black Mormon fired by Brigham Young University for compiling an anthology on the Mormon church's historic demonization of African-Americans. It was an eye-opening read.
