Japanese internment during WWII is laughably incomparable to the damage inflicted upon African Americans over the last few hundred years or so. I think the OP meant age-range, or at least that was how I initially interpreted. Though I'm not sure that's true either. Even if OP meant something different, there are waves of Cubans, Chinese, Hmong, and many others. Who knows?
To borrow some momentum from modern pop culture via Bane from Batman. Japanese-american culture resisted the influence of darkness inflicted by the american culture that was consumed (temporarily) by the darkness. African American culture was seeded in that darkness. One culture resisted hate due its experience with hate, for the other, hate is all it knew.
