I think the whole notion of historical apologies cheapens apologies in general, and while I can regret something my great grandfather may have done, I do not know that it is appropriate for me to apologize at all, and certainly seems silly for me to apologize to someone else's descendants. (One of my forebears was on Sherman's March to the Sea, so who knows how many Southerners I might owe an "I'm (collectively) sorry" to ...)
But as apologies for ancestral wrongs go, this one takes the cake:
Sorry we ate your forefathersNow everyone can finally move on, I guess.
The descendants of Papua New Guinea cannibals who killed and ate four Fijian missionaries in 1878 have apologised.
