I would imagine it's less about any given statue and more about it being indicative of a kind of cultural revolution. It's not necessarily a bad tactic, though imagine asking people if they knew George Floyd existed before the video. If people followed that heuristic and didn't get worked up into a frenzy then we wouldn't have had the riots and largest YoY increase in homicides in US history. Though I think the video was more a catalyst for unleashing the pent up frustrations of a populace forced under house arrest, living in fear of a virus, economic uncertainty, etc.
