You seem to be implying that america is post racial and some of just won't let it go. And you seem to have read your own biases into a very objective and clear point. That point being, stop banging on about how terrible it is people get defensive when you use offensive terms. If your response to that is "but it's not", followed by yet another academic definition of "privilege" is.. stop. You've missed the point. Offense is taken, not given. If your goal is to have a frank and honest discussion with someone rather than attack them, you do not lead off by using terminology that is racially charged (as if anyone can choose their race), minimizes someone's struggles in life (of which you necessarily know nothing), implies guilt (however slight), and which is frequently used in bad faith to shut down discussions anyways. That may not be what you personally intend, but that is what the audience hears. Act accordingly.
