Liberal cable network MSNBC has a way of offending conservatives in the least productive manner possible. Case in point: On Sunday Melissa Harris-Perry invited a roundtable of comedians to dissect a family photograph of failed GOP presidential candidate Mitt Romney, who in the photo is holding on his right lap his newest baby grandson, Kieran Romney. Kieran, who is adopted, happens to be black. Which was enough for Harris-Perry’s guests to make fun of how the Romney family, much like the Republican Party, is mostly white. It’s not the dumbest thing MSNBC has ever aired (that would be Morning Joe), but still: It’s a baby.
