People who want something "let go" typically only want such things because to remember it would be to hold them accountable in some way.

Best case scenario is that this loser wants it "let go" so he can forget his complicity with authoritarian measures. Worst case, he was actively on the side of authoritarian measures, still is, and fears if people are actually held accountable.

EDIT: Openly calls himself a cultural marxist, it's definitely the latter in some form.
