And the story of racism is everywhere.
I'm currently reading Breaking Bread with the Dead by Alan Jacobs which deals with a lot of these issues and our presentism arising from dismissing the past as uneducated, unrefined, almost an insult to our current mode of thought.
He advocates a balanced approach whereby we don't forgive the ignorance of the past but try to look at the good in a slightly different context. It's the whole "can we like someone's work while despising the person" argument.
Dismissing something as a product of its time does us a disservice because we do not properly explore why and learn the lessons that teaches.
