None of the edit suggestions or controversies were racist or biased. It is clear that ardent supporters of the BLM movement simply want to shape the historical record in the way they want to. And Wikipedia will probably side with them.
How is mentioning Floyd's past criminal record on his biographical page (not even on the "Killing of..." page) a detraction from his death? Are we just going to edit Wikipedia to remove anything that detracts from people we idolise? Wikipedia should present the facts (all of them) and that is it. If the facts detract, then maybe there's a reason for that. That doesn't change the fact that they are facts.
When it comes to political events, you cannot take Wikipedia as a reliable source anymore.
The sad fact is that the people who have the most time to give to wikipedia, are typically the most biased.
