Evil gets forgotten all the time.
Swept under the rug, ignored by “people of consequence”, and just general indifference on the part of others who remain purposefully uninformed. Or maybe it is just that the statute of limitations has run out.
Meanwhile, the perps continue to enjoy freedom and the fruits of their unlawful activities, and there is none who speak for the victims.
Even “cold case” crimes remain crimes.
The President did not say that evil would not or could not be forgotten.
He said that it should not be forgotten, a very different concept indeed, and one I agree with completely.
Obviously evil deeds are often covered up successfully or rationalized away, but they remain evil and should be exposed and remembered as best we can. Even, perhaps especially, those committed by “our side,” whatever that side may be.
Though evil should always when possible be remembered in context.
