Statues and street names are intended to celebrate people, that's what the objection is to. Should Germany re-erect statues of Hitler because removing them was 'sanitization' (done by the Allies during the "denazification" of Germany)?
I rather liked Banksy's suggestion, put the statute back up, then erect more statues showing people pulling the re-erected statue down. That would be apposite, no erasing of history but rather a statement of "Look we used to celebrate this fellow but then we didn't and here's the reminder of all of it".
Then explain to me "Memorial in memory of the British, French and Russians who fell during the battle of Inkerman on October 24" (British and French were invaders), that russians restored quite recently. They have tons of such.
Or a monument to Genghis Khan who conquered Russians in very bad way. He would not have a statue earlier, while the pain from his actions was still felt, but later, they did it when they were able to look at the events of those times more independently. Now they understand, in those days, there was a different truth, a different assessment of actions. For example, the fact that the actions of Genghis Khan was possible because of weakness, and reminds people to be more united against aggressors, and etc.
They have a lot of such monuments too.
A monument is a historical landmark, if it is made to a bad person and irritate significant part of population - it can be transferred somewhere to the backyard until better times, but people should not try to rewrite or delete part of the story, by destroying or altering monuments.
There is exception to pointless, countless and useless monuments that was erected as part of "cult of personality" to dictators, but even those, good to keep some in museums, with proper explanation.
Perfect words of Winston Churchill: “A nation that forgets its past has no future”.
People should stop being hypersensitive idiots who are offended by everything around them.
