I think that everyone should learn from crimes committed by all nations, not just those that they have some weak genetic link to, as if genocide was a potentially heritable trait like eye color. My own ancestors were Irish, for example. Obviously, the Irish people suffered greatly at British hands. Does that mean I should learn less about British crimes, or take them less seriously, than a classmate whose great-great-great-great-grandparents happened to be British instead? I would say no, and that everyone should learn about British successes and failures (and why they happened, what motivated them, etc.) equally.
