If The British Did What Progressives In This Country Wanted

How many world famous buildings, castles and monuments would be torn down? Would castles owned by nobles who rebelled against the crown be torn down? Would houses where servants once worked be torn down because the descendants of said servants were offended? Would the Tower of London be gone due to it being a place where scores of unjust murders took place by tyrant kings?

Would the statues of kings who enslaved or murdered people be torn down? What about those of medieval or renaissance nobles who had servants who were the equivalent of slaves? What about those who advocated for and expanded the British Empire? That would include famous statesmen like the Duke of Wellington, Benjamin Disraeli and Winston Churchill.

The British have a history full of rebellion against the Crown, feudalism, class strife, war and empire. Unlike us, they don't seem to be trying to erase the uncomfortable parts of their history.
