I wasn't alive during slavery, and as far as I know my ancestors were Native Americans and post-civil war European immigrants. I wasn't born until 1969, so I accept no blame nor responsibility for slavery, Jim Crow, segregation, etc that happened before me. There are huge numbers of people of different races, religions, nationalities, etc who have become great successes - there's no excuse these days, particularly with all of the affirmative action, grants, etc minorities are afforded. Slavery and other forms of oppression have gone on all over the world since the beginning of time, and still do. I have no doubt at least some of my ancestors were oppressed and mistreated one way or another here and back in Europe. It all happened a long time ago before any of us here alive in the world today were born. Time to move forward.
