Embracing the good things of the past does not require for us to embrace the less good things as well. It is possible to cherish the good, and leave the bad as a remnant to gather dust rather than a relic to invite worship.
Learn from History rather than Ingest the Myth
It is not erasing history or rewriting history when we acknowledge that history if full of imperfect people. Nor is it protecting history when we whitewash over the sorrowful things imperfect people did or wrote before better practices and choices were available.
What we should strive not to do is to celebrate the bad as well as the good. We should carefully evaluate what history teaches rather than simply ingest the tale that we call history.
