In regards to slavery in America, I shall point out that slavery was not just those of a certain color. I lived on the Mainline. The grand railroad interconnecting the suburbs to Philadelphia. Every so often markers would appear. Many are unmarked and may be mass graves I looked into it and found that the laborers who helped build the railroad were indentured and consisted of Chinese,Irish, Scots and Blacks among others.
Excellent post.
I just bookmarked it on my FR homepage.
