That's astronomy, not astrology. A visual alignment, not an astrological alignment.
The moon acts as a trigger, triggering an astrological "event" set up by the slower moving planets. It passes through that Jupiter, Saturn, and Pluto parade (Venus is passing over Pluto right now) once a month. Right now, the moon is conjunct Neptune, forming a minor grand trine (excitement/harmony) with Venus/Pluto at the apex and Mars trine (Moon/Neptune). How it affects individuals depends on where it is in the birth chart.
Considering Pluto represents power and hard truths, while Venus is Harmony, Mars is action and the Moon/Neptune are about intuition, one's inner world, including illusions, perhaps this configuration has something to do with people waking up and getting mad.
