"340 years of America's white racial terrorism and 60 years of a weak national response is not my FAULT. But, as a beneficiary of that process, it is my RESPONSIBILITY to learn its historical details, and how/why it gave my family and me enormous advantages. With that knowledge, how can I not say I'm also responsible to try to fix the unfair system?"

THIS!! I would only modify it to say, 'responsible to at least try to elect people who will fix the unfair system....'
