Before Obama is done, Mao is going to seem like Mother Teresa.
You mean Mao would then seem like a person who enjoyed suffering, surrounded themselves with it, made suffering people sleep on cots until they died of whatever afflicted them because they thought that brought them closer to God and is now worshipped as being a great person by millions of people?
Besides the bringing them closer to god part, he already sounds a fair amount like her.
Maybe comparing him to someone who actually cared about people and suffering would have been a better idea, like Jesus.
