I don't like the possible slippery slope of the movement as I could see several decades from now people wanting something like the Tomb of the Unknown Soldier taken down because it casts Germans etc. in a negative light.
On the other hand, how many people today actually care about Cornwallis so much that they need to see him in their daily lives. I would understand it if instead of displaying these kinds of statues in parks they get moved to museums or public locations specifically focussed on history and education.
Until now, I had never heard of him.
