This is all interesting as it indeed could lead to removal of statues of presidents who, say, owned slaves. Let each community/neighborhood decide what they want to represent and let others criticize it. That's America.
Some are comparing this to religious pieces in public parks. In that case, allow all religions/belief symbols or none, but public properties should not be allowed to sponsor/favor a specific religion. If there is any comparison, perhaps allow counter pieces next to Confederate monuments or allow none. Either way, taking down 'history' that isn't appreciated by its residents is fine, let them duke it out within themselves and if taking it down is the decision, so be it. Even if a president because of owning slaves.
