(CNN) - Of course a memorial to Martin Luther King Jr. was going to be controversial.
The man himself was controversial, notes LaSalle University sociology professor Charles Gallagher. King - bound up with issues of racial and economic inequality that spotlight America's worst sins - is a "Rorschach test," Gallagher says, that people see in King what they want to see.
Still, few of the organizers of the Martin Luther King Jr. National Memorial in Washington may have expected that every little detail would be so scrutinized, criticism that has continued right up to the first Martin Luther King Jr. Day since it opened last fall.
Late Friday, the Department of Interior - which has jurisdiction over the memorial - announced a quotation in the memorial's King sculpture would be changed. This action followed months of complaints about the language of the quotation, which had been paraphrased from a passage in a King sermon.
