It’s designed to sound plausibly benign to people who aren’t paying attention — for example, anyone who didn’t stop to ask why someone felt the need to answer a question nobody was asking – but black people in the US are unsurprisingly not given the opportunity to be oblivious to racism. Ask a black person or a Jewish person what the neo-nazis are doing and they’re far more likely to be at least somewhat informed because a lot of people in their communities can’t afford not to be.
