Yes, we have reached a point in our culture where a presidential candidate is forced to apologize for espousing a belief that all lives – black, white, other – matter.

Phoenix (CNN)Democratic presidential candidate Martin O’Malley apologized on Saturday for saying “All lives matter” while discussing police violence against African-Americans with liberal demonstrators.

Several dozen demonstrators interrupted the former Maryland governor while he was speaking here at the Netroots Nation conference, a gathering of liberal activists, demanding that he address criminal justice and police brutality. When they shouted, “Black lives matter!” a rallying cry of protests that broke out after several black Americans were killed at the hands of police in recent months, O’Malley responded: “Black lives matter. White lives matter. All lives matter.”
