What’s the real story behind the statues in Parliament Square?

Parliament Square is one of the most famous places on earth. It’s home to revered figures such as Winston Churchill who are lauded as “British heroes.”

Whereas the removal of statues of Confederate figures in the US can be seen as an ugly act of triumphalism and dominance, which may or may not have any actual connection to preserving the institution of slavery, where are the social justice warriors in the cities of London and Washington DC?

Perhaps they are only interested in triumphalism and dominance or they would correct their own myths and false icons before demanding that the vanquished adhere to their narratives.
