If you haven't already, please read The Debriefing's take on the Kelly Tilghman/Tiger Woods snafu. Click the links -- they suck and are scary, but do it anyway.
I'm immensely grateful to work for an organization that actively fights social injustice in a neighborhood riddled with examples of such injustice, but I know that sometimes I forget how pervasive ignorance about such matters can be. And, as The Debriefing points out, ignorance is no excuse for grossly insensitive comments like Tilghman's. Ignorance fosters cruelty by enabling it to exist unchallenged.
