Didn't is past tense. How can you be sensitive about something your grandfather went through? My indian relatives didn't get put in chains, those dudes got shot man. They got shot or they received blankets with small pox in them. But why should I be angry or upset or sensitive to it today? Most people go out of their way to be extra courteous to minorities. But the same slim number of people that are racist bigot assholes are matched by the number of minorities who are the exact same way. I'm not a big fan of double standards.
