I have no evidence upon which to assume that Xingu is stubborn or lazy, and continue to consider that unfair of you.
As for judging material based on the source, i consider that perfectly reasonable. I don't consider the member to whom you refer to be reasonable, but i've got him on "ignore," and won't comment on any of his posts, as i now cannot read them anyway.
Criticizing a source is reasonable. I've just come from a post in which i criticized another member who used a "Free Republic" article as a basis for criticizing Snopes. In the first place, the Freeper article did not address the subject of the Snopes article. In the second place, "Free Republic" is a notoriously rightwing and unreliable web site. I consider criticism of the source reasonable in that case, and clearly stated why i consider Free Republic unreliable, and why i consider Snopes reliable.
As you know, i chiefly study history. There is an "historian" by the name of Howard Zinn.
You can read about Zinn in the Wikipedia article. Zinn is well known (notorious, i would say) for his "People's History" series. More than 20 years ago, having already heard bad things about Zinn, someone i knew gave me a copy of his
A People's History of the United States. I tried to read it, i truly did, but i eventually gave up in disgust. Zinn is most often attacked by rightwing types, and anti-communist types. For as much as it is distasteful for me to find myself in such company, i agree with the comment by Daniel Flynn when he says of Zinn that ""his is a captive mind long closed by ideology."
I will give you an example. In the beginning of his
A People's History of the United States, Zinn claims that Columbus began a genocide against the "Indians" of the Caribbean. This is disingenuous, and a willful distortion of history. When Columbus arrived in the Bahamas, the Spaniards met locals whom they called
los Indios, the in the belief that they had reached the East Indies. More specifically, they referred to these people as Arawaks. There are actually many tribes which make up those whom the Spaniards refer to as Arawaks, and many other tribes to whom the Spaniards referred as Caribs. These latter are now believed to have entered the Caribbean from the south, and to have killed (and eaten) the Arawak men they encountered, and to have taken the women as wives. Long considered by leftwing historians a propaganda, the fact that Carib women spoken what was very nearly an entirely different language, and which was comprehensible to the Arawak of the Lesser Antilles supports the view that Carib men had taken them as slaves and kept them in subjection.
When Columbus and the Spaniards arrived, the Arawak had been under attack by the Caribs for more than a century. They were impressed with the apparent might of the Spanish, and lead them to the Greater Antilles--to Hispaniola (now Haiti and the Dominican Republic), and to Cuba and Jamaica. The brother of Columbus was pretty damned bloodthirsty, but i don't consider it reasonable to condemn him for the acts of his brother. There is no doubt that the
Conquistadores made slaves of the Arawak (the Taino of Cuba and other tribes they lumped together under the heading of Arawak). One on of Columbus' later voyages (1502), the friar Bartolomé de las Casas was his cleric. Las Casas edited and published Columbus' journals, and published
Historia de las Indias. He was a tireless worker for the end of slavery for
los indios, on the basis of the idea that if they converted to Christianity, they were entitled to at least the protections afforded to
peons in Spain. Frustrated for most of his life, and often threatened with his life, his efforts nevertheless culminated in the foundation of the Indies Commission, a bureau of the Spanish Inquisition whose duty was to assure the "decent" treatment of the Indians. We might not consider the living conditions of peons to be "decent," but by the standards of the day, it was an enlightened attitude, and certainly better than the slavery which they endured in the beginning.
It is on the basis of the writings of las Casas that Columbus is habitually condemned. But nowhere in his writings does las Casas condemn Columbus for practicing or condoning slavery, or the slaughter of the native populations. Zinn makes his accusation and disposes of Columbus as a genocidal criminal in two short lines at the beginning of his pathetic pseudo-history. You can't even find a reference in the book to support the charge he levels against Columbus. I have no particular brief to defend Columbus, but i am as disgusted by distortions of the historical record when practiced by Zinn as i am when practiced by anyone on the right.
Some of the most unrealistic and persistent of historical myths surround the story of the clash between Europeans and Amerindians. Zinn not only does nothing to correct the record, he perpetuates what are unsound stories and no history at all, and has introduced the phoney "long-suffering, gentle Indian" myth to newer generations, and all in the name of his ideological prejudices. It is worth remembering that Marx considered history to be a malleable subject, which should be enlisted in the cause of ideology, without regard to probity in academic research and reporting.
Therefore, if someone comes up with Zinn as a source, i will immediately condemn their claims on the basis of the source, and am always prepared to back up my criticisms of Zinn.
It is always perfectly reasonable to condemn a source.
EDIT: It is of course, also perfectly reasonable to point out that many Indians died from being enslaved by the Spaniard. It is also reasonable to point out that the
Conquistadores were most of them veterans of Cordova's campaigns in Italy, and that they brought malaria from Italy to the "New World." At least as many, if not more, Indians died from malaria as from the effects of being enslaved. You will never learn that by reading Zinn, though.
