Protest floats

The term "protest floats" is used to refer to the ghost demonstrations that took place at the Ministry of Magic Headquarters, most likely during Grogan Stump's term as Minister for Magic from 1811 to 1819. If that is the case, it is most likely the ghosts gathered there to protest against being categorised as "Beings" by the Ministry, when they were so clearly "Has-Beens". The Spirit Division was created shortly after.
