All totally reasonable things to say.

Yeah, that's the explanation, but we shouldn't confuse that with justification.
What puts me off about the reaction I'm seeing is more abstract than the details of this particular case. It's the same feeling I have when I see casual anti-White racism, justified as legitimate only because of the existence and history of white supremacy. It's filial guilt and collective guilt put on one individual who didn't perpetrate the crimes that are the actual source of the anger. And it's the cultural normalization and even promotion of such perverse group-based moral systems that I am speaking out against.
