I agree each generation is more educated and it does indeed, matter less. But there will never be a "completely". A society must always be reminded of their history in order to move forward. The blacks will never let us forget slavery, the Jews will never let us forget the holocaust, the LGBT will never let us forget the Stonewall riots; to name a few.
