When you are talking about larger social trends and human behavior (which is what most of us have been doing so far as I can see), generalizations are part of that. Every human action is, to some degree, unique. No one is disagreeing with that. But even in those unique actions there can be shared thoughts, trends, instincts, biases,prejudices, etc. Talking about those shared parts is not to make each person or action "indistinguishable" from one another, but to avoid getting stuck in the weeds. Ultimately none of us can know if Kinsler is actually racist. It's hard to even know if our own selves are racist and how our biases alter our perceptions, thoughts, and actions. So trying to plant your flag in what seems to be "Don't call me biased, you don't know me! (Or Kinsler! Or whomever...)" is really missing the forest for the trees. That's not what nuance is. That's just confusing what the object of discussion is. The question is whether this particular tree wandered into the forest of racism. I think it did. And there is plenty of general evidence about the biases we have to support that conclusion.
