I was hoping my sarcasm was evident. What I posted is essentially what this person is doing - ignoring the mountains of evidence and facts of the situation all of which point indisputably towards it being about race. Then, having ignored all that, they cast doubt on it being about race.
It’s a typical tactic of the right. Ignore all the overwhelming evidence in a situation and then, once that’s done, declare that the conclusion obtained from all that evidence is invalid because “there’s no evidence for that.”
