As is their right. (Not that I'm advocating it.)
No idea why people are getting so hot under the collar about a mere suggestion that a statue be removed.
(I, for example, would be perfectly comfortable with a decision to remove the statue of William Crowther, because I have this peculiar belief that nothing good that a man does as premier of Tasmania can compensate for the obloquy he deserves for sawing off a corpse's face. But I am a bit old-fashioned about corpse desecration. I don't think a statue of Tom Wills should be pulled down on the strength of a scurrilous, inaccuracy-riddled article in an American newspaper, but I have no problem with other people thinking it should.)
It's only a problem when discussion spills over into people imposing their will and e.g. vandalising statues. Even worse when that behaviour is validated by people in positions of responsibility (whatever happened to that van Diemen woman?).
