To what end this moral instruction? I was the choir, already agreeing with the sermon and finding scant edification in it. And I imagine the Penumbra's core audience--the black citizenry of the Twin Cities--have more than a passing familiarity with our society's peculiar racial politics. If there are people sincerely in need of such earnest, introductory overviews of the experiences of communities of color in Los Angeles, I suspect that they're not likely to be found in the seats of the Martin Luther King/Hallie Q. Brown Center of St. Paul.
