We are responsible for the sins of the present, both the individual sin of prejudice and the social sin of racism.

They shut the door on something unpleasant, in the process heaping blame on isolated individuals that ought to be borne, or at least processed, collectively.
The president doesn't "love" America? Would that it were true. Would that the president felt a responsibility to the global future and, at the same time, could summon our real past, grieve for its victims and vow with every fiber of his being to atone for our history of slavery and conquest: the "white terrorism" of manifest destiny. Would that the president didn't "love" our myths.
