Ah, but you forget . . . only the slavery that existed in the USA was actually bad. Everywhere else it was AOK!
Seriously, do you ever hear slavery condemned without it being American slavery? Do you think these other countries are still beating themselves up over it?
Only in countries like Jamaica, where the vast majority of the population are descendants of slaves.
Condemning Jamaican slavery is easy and cheap.
The fact that America acknowledges the moral flaw of its slaveholding past is a good thing, it betokens a national conscience in working order - the problem is that the American left completely ignores the great sacrifices America made to put an end to slavery.
The American left ignores the fact that America is the only country in the world where the descendants of former slaves enjoy a standard of living and a social status higher than that of almost any historically free demographic group.
The United States is not alone in owning up to a slave-owning history at all.
In contrast, some people should stop trying to sweep the history of slavery in the United States under the rug.
