Yes, but when asked, "do you see a place for this sort of historical investigation of the consequences of past actions?" they said that the answer depends on whether it is "wielded as a weapon", which seems to imply that the answer in that case would be "no" - that if given a choice between only the options of being kept secret or being wielded as a weapon, they would prefer it be kept secret.
You're somehow leaving out the option that I mentioned of "use as a text book." My answer was to highlight the concern that intent/purpose and motives are important, e.g if someone going to use the reminder of history as a weapon to rally anger and hate, or to guide rational, reasonable discussion?
Yes, I understand that that's your preferred option. But your answer seems to imply that if people were going to use history as a weapon, then it would be better for it to not be known at all. That is, your order of preferences is Text Book > Secret > Used as Weapon.
If the purpose for 'historical investigation of the consequences of past actions' is to rally anger and hate in the present, then no, I would prefer it kept 'secret'. Mainly because I would have no faith that the investigation would be objective or have any redeeming qualities.
