The academic left promotes all manner of wacky ideas, not the least of which is slavery reparations. The idea is that white Americans ought to collectively write a giant check to black Americans in atonement for past mistreatment. A bit of introspective genealogy demonstrates the foolishness of such a policy.
I am a quarter Irish, a quarter Danish, a quarter German, and about a quarter English. My Irish ancestors suffered first from Danish Viking raids and then from a murderous English occupation. It is quite possible that some of my English ancestors were part of Cromwell's army whose invasion of Ireland resulted in the death of nearly a quarter of the Irish population.
Examining my ancestry, it would seem that as a descendant of Vikings, Englishman, and Irishman, I owe reparations to myself. Every group of people have at some point committed transgressions against another group. To grant one group reparations for past suffering would set a destructive precedent that could ultimately compel me to write myself a check.
