Protests over the police-involved killing of George Floyd have branched into multiple efforts aimed at societal change, including the dismantling of statues, monuments, and memorials.

Demonstrators are once again actively trying to take down monuments to Confederate figures but it doesn't stop there. Vandals have also targeted statues of Christopher Columbus, Thomas Jefferson, and even Abraham Lincoln and Winston Churchill.

Is this just about removing monuments to people that activists believe are unworthy of the honor or is this there a much deeper and more troubling rationale for removing these historical markers from the public square? Where else have we seen such efforts in history? And how do those wanting to defend and present the real history of the United States fight back?

We ask these questions and more to Jarrett Stepman, reporter for The Daily Signal and author of "The War on History."
