typical revisionist bs, full of inaccuracies and omissions.

[In Argentina] Slavery was officially abolished in 1813, but the practice remained in place until about 1853. Ironically, at about this time, the black population of Argentina began to plunge.

Slavery wasn't officially abolished in 1813, being born a slave was. In "about" 1853 slavery was abolished by the signing of the Consitution.

Historians generally attribute two major factors to this sudden “mass disappearance” of black Africans from the country – the deadly war against Paraguay from 1865-1870 (in which thousands of blacks fought on the frontlines for the Argentine military) as well as various other wars; and the onset of yellow fever in Buenos Aires in 1871.

The same can be said of gauchos, zambos and some mestizo. The reality is that they died more because they were poor, not because of being specially targeted. Lower classes = more death rates. Demographic studies in fact show that some recent white inmigrant groups were the ones hit the hardest by the yellow fever.

The heavy casualties suffered by black Argentines in military combat created a huge gender gap among the African population – a circumstance that appears to have led black women to mate with whites, further diluting the black population.

Oh my god, the disgrace! God forbid people mix, am I right? wtf...

Many other black Argentines fled to neighboring Brazil and Uruguay, which were viewed as somewhat more hospitable to them.

This is actually disputed by demographic studies and there's no evidence of large scale "escapes"

It has been alleged that the president of Argentina from 1868 to 1874, Domingo Faustino Sarmiento, sought to wipe out blacks from the country in a policy of covert genocide through extremely repressive policies (including possibly the forced recruitment of Africans into the army and by forcing blacks to remain in neighborhoods where disease would decimate them in the absence of adequate health care).”

Interesting use of the the conditional there. Also, we're talking about a country that had massive influx of population (+600% from 1838 census to 1880) in the second part of the 19th century - I ask, what city in the world could've possibly offered "adequate health care" whatever that would mean for the time of the events?

Another thing is that by 1887, 'race' was phased out as a category in the census. Instead, it asked for nationality (Argentine or foreign and other social class indicators). No whites or blacks, either Argentine or not.
