With all due respect, what a bullshit point. Slavery can and should be talked about in a true historical context. But the American Black slave experience is not unique; I'm not dismissing it, but it is not unique.
I'd prefer to see slavery discussed in the here and now and discuss how we can eradicate it from the face of the planet. But that won't happen in America because slavery in America = racism. That's what is taught in school and it's a fallacy.
Yet race never had anything to do with slavery. Slavery was based on labor needs.
Slavery goes back thousands of years. Slavery exists today. And sadly slavery will exist for centuries to come.
Should the existence of slavery from the past, present and future prevent us from utilizing and embracing the great teachings of men of history from centuries past?
Should we ignore the teachings of great philosophers such as Plato or Aristotle because slavery existed in their day?
Should we dismiss the Magna Carta?
I think not. I could list a thousand more examples but I'm only on my second coffee.
