Yes, look, some might find me very insensitive for making a joke referencing an atrocity of the past. Yes, I am probably insensitive.
But some of my relatives were badly effected by William of Normandy crossing the channel, and the Norsemen raping and pillaging East Anglia. Some of my relatives were Swiss, the Goths have a lot to answer for, not to mention those Roman Legions who cut a swathe of death and destruction across Europe.
Whats the statute of limitations on these things anyway? At what point are we now allowed to accept these things happened, without having to own some guilt for them, or blame others for the injustices?
