There's a difference between a huge feat of engineering from thousands of years ago and a tacky statue that was erected barely outside of (or sometimes even within) living memory.
As was established earlier, an statue built 10 years ago is very different from one built 150 years ago. A tacky statue built 10 years ago is not worth much today as a historical memory.
To make it simpler, is it acceptable to destroy a tacky statue of a slave owning roman, with the only saving grace being that its a century old?
