George Floyd is practically a saint in the eyes of many, despite all his flaws as a person.
That was never the point of the protests surrounding his death. The point was to call out police brutality. This was true of all the other anti-police brutality protests before George Floyd as well, regardless of whether the victim had a perfect past or not in each case. The press, both local and national, humanizes some victims of state or corporate violence, while demonizing others. Seemingly without noticing, people too often create tiered systems of moral worth by trying to find “the perfect victim.”
This ill advised search for the perfect Christlike victim, and its corollary desire to smear those with less than perfect pasts, makes humanity conditional, further entrenching negative stereotypes and destructive narratives about entire communities. The difference between a victim of systemic injustice who made mistakes in their life and a person who gets deified despite their mistakes is incalculable. The demonization of George Floyd in the wake of his death was IMMEDIATE. The media did not even wait for his blood to be cold before they started digging up his arrest record, etc. The lionization of the founding fathers on the other hand was overwhelming and immediate, in spite of their slave ownership, and an entire American civil mythology was constructed around that image that for many is still considered unquestionable. That's the difference. You're assuming a total symmetry of context between the contemporary victims of systemic violence and the actual ruling class founders of American society.
