Here's an opportunity to practice philosophical detection. Consider the headline and main quotes of this article:

African Union criticises US for ‘taking many of our people as slaves’ and not taking refugees | The Independent

“The very country to which many of our people were taken as slaves during the transatlantic slave trade has now decided to ban refugees from some of our countries,” said Nkosazana Dlamini-Zuma.

The statements of politicians worldwide are loaded with moral trickery... fallacies intended to confuse you so that you simply concede the point.

I wrote the following as a comment to this article on a friend's wall.

I must reject the person quoted as a person who panders to the notion of Ancestral Guilt. His assertion deems Americans today to be as equally guilty of slavery as the ones who actually perpetrated it in the past.

Effectively, one could abstract this and say that the speaker believes that You and I assume moral guilt for the actions of those who came before us. This is a mess, because where does it stop. Could the same tactical maneuver be used to re-assign the blame earned by Muslims that kill onto the ones that do not?

Further, what of the African collaborators involved in the slave trade?

"The historians John Thornton and Linda Heywood of Boston University estimate that 90 percent of those shipped to the New World were enslaved by Africans and then sold to European traders. The sad truth is that without complex business partnerships between African elites and European traders and commercial agents, the slave trade to the New World would have been impossible, at least on the scale it occurred."

"...The African role in the slave trade was fully understood and openly acknowledged by many African-Americans even before the Civil War. For Frederick Douglass, it was an argument against repatriation schemes for the freed slaves. 'The savage chiefs of the western coasts of Africa, who for ages have been accustomed to selling their captives into bondage and pocketing the ready cash for them, will not more readily accept our moral and economical ideas than the slave traders of Maryland and Virginia,' he warned. 'We are, therefore, less inclined to go to Africa to work against the slave trade than to stay here to work against it.'"

Perhaps history forgives the villany of African slavers because there is no political gain in flogging it.

Much as I agree that Trump's order is an immoral clusterfuck, this article's premise is objectionable due to the moral shell game described above.
