No, you are right, they were a group of greedy Europeans, but then the rest of the world were greedy too.  Africans sold their own people into slavery.  The Arabs facilitated the African slave catchers. Everyone was greedy, callous and indifferent.  But, for all other nations, except Canada, they have got over it.  We, on the other hand seem to enjoy the hair shirt and flagellating ourselves, trying to rid ourselves of what the Eastern intelligentsia have deemed out colonial past.  Why not say; 'Yes, we know it was wrong" and get on with life.  There is a lot to celebrate about Canada, so forgive our fore-bearers their sins and get on with life.
