Convinced of what? I was asking you a question.
Should you be proud of your family? You had no control in that. By your previously stated standard, you shouldn't.
I do not take credit for the actions of my ancestors....good or bad. I feel kinship with my family members.....an emotional attachment and shared experiences. I feel joy when someone in my family succeeds.....a little more than if it were someone who is not in my family. But I am not running around looking for compliments over my father's military service or my grandmother's distinguished service to her community. I had nothing to do with it.
My wife and kids.....the family we have built together....yep. I am proud of them. None of them are white, by the way. Cool, huh!
