Even a statue of Caligula has value, if only to remind us of who he was and what he did, having too much power.
These people demand to wield that kind of power with similar awful potential. They need to die.
Not sure that's warranted; but I recall when rioters tried to rope and pull over the Andrew Jackson statue across from the White House during Trump 45, he passed a law promising a 10-year sentence for attacks against cultural monuments. The statue-pulling stopped almost completely.
