Re the Colston statue, the people of Bristol never wanted the damned statue in the first place. The statue was raised by a guy called James Arrowsmith who tried to fund it by public subscription, and failed. He had to put in the last £150 of the £1000 it cost himself as he couldn't get enough from the residents of Bristol to fund it.
There had been long running petitions in Bristol for its removal (and the renaming of Colston Hall among other commemorations of Colston), this from a friend of a friend in Bristol
Chucking Colston in the river is one way of dealing with him that has brought him out into much better discussion of his legacy and the 19000 people who died in transit and were just dumped in the sea as well as the people who were sold once they got there, how would we react to a statue of Jimmy Savile?
As for the plinth? Put Wallace And Gromit on it, with the train!
