Even true facts can be used for bad purposes, and even uncomfortable facts are worth knowing. This philosophy is what leads to things like denying the Armenian genocide, or denying the rape of Nanking.
Are those atrocities being used to demonize the descendants of the perpretrators? Not that I can see. Therefore, I take no issue with bringing them to light.
It seems you'd be okay with using true facts to incite racial or religious hatred, something which is against the law in most western countries.
