At some point in the last few years, journamalists stopped promising "lunar eclipses" and took to calling them "blood moons" instead. It is as if they are following the lead and accepting the framing of the crazy-pants fundamentaliban US preachers with their End-of-Days eschatology (which appears to be all about "the moon becoming as blood"), i.e. Revelation fanfic.
That is unpossible, however, for it ascribes some influence to a tiny fringe of demented grifters, while requiring that our media are so lazy that they simply parrot back whatever phrases they have heard most recently. I am sure that "blood moon" has always been the term of choice.
UPDATE: Science fiction writers in 1973 had some weird pessimistic notions on how psychotic and isolationist American culture could become. Disch's moon-themed "Anthology of Political Forebodings" includes, among many other fine stories, Sladek's "The Great Wall of Mexico" IN ACCORDANCE WITH THE PROPHECY.
