I would like to see the Martin Luther King monument removed from the Mall. Not only was King himself a preacher, he led a large religious organization and is named after the founder of the Protestant Reformation. Clearly the MLK monument is a religious symbol lifting up for veneration a ordained religious leader of a particular sect over all others.
What's next? Pope John Paul II arguably was critical in freeing more people (all of Eastern Europe and Russia, hundreds of millions of people) from a more repressive system (gulag era Soviet Communism) than King's mere 20 million American blacks freed from Jim Crow.
Can we erect a John Paul II statue on the Mall?
