jeremiad

1: A long, mournful complaint or lamentation; a list of woes.

2: An utterance of grief or sorrow; a complaining tirade: used with a spice of ridicule or mockery, implying either that the grief itself is unnecessarily great, or that the utterance of it is tediously drawn out and attended with a certain satisfaction to the utterer.

In 1978, Moorcock made the conflict explicit in a jeremiad against the old inkling entitled “Epic Pooh” (as in Winnie-the-Pooh), which accused Tolkien of propagating a ­sentimental Luddism while blithely promoting war.
