Why should a city, state, or federal government put statues in public parks? Doing so addresses no plausible market failure, while using taxpayers funds and, as demonstrated tragically over the past few weeks, generates controversy, polarization, and violence. Thus governments should take down all statues, regardless of their political implications.
This is not “erasing” history but instead leaving it where it belongs, in the hands of private actors and mechanisms. Historians, textbook authors, universities, learned societies, the History Channel, and many other individuals and organizations can all present their own views of history and battle for the hearts and minds of the public. Government statues are government putting its thumb on the scale, which is one step down the slippery slope of thought control.
