Why is there an obligationto "celebrate" any reversals of racism? All that happened, in each of those cases, was white people returning something their ancestors had stolen. Those were not occasions of celebration, and white people were not entitled to gratitude simply for returning what was stolen?
In fact, what is the purpose of this conservative fixation with "celebrating America"? How can any celebration of anything be valid if it is made cumpulsory? Cumpolsory celebration is the kind of thing they do in North Korea, for god's sakes.
