I strongly disagree. As the ACLU attorney told me, "Do for one, do for all, or don't do at all."

Take every single monument down. Every single one. Somebody in the U.S. will disagree with it.  Cannot have it both ways. 

Martin Luther King I liked, but he had enemies from both the Unions as well as the illegal alien laborers. Take his memorial down.

Vietnam War - many people opposed it. Take down the memorials to that. All of them.

Go here, there is a bunch more needing removed. Preferably under the cover of darkness, following Baltimore's lead.
