You may or may not be aware of this, but many active slavers, among them John Taylor of Caroline, described slavery as an “evil” while simultaneously opposing, both in their words and their deeds, all immediate efforts to end it. “Evil” is a word which has many shades of meaning, and in the 18th and 19th centuries it was far more commonly used than it is today to refer not only to deliberate acts of wickedness, but also to more generally bad conditions such as hurricanes, earthquakes, or general ignorance and folly. Many anti-abolitionists and slavers viewed slavery as an “evil” in the latter sense (in that they would rather be rid of it, but did not believe that white slavers had any immediate moral obligation to stop enslaving the black people that they held captive). Robert E. Lee, for example, was of this school of thought (the letter in which he famously described slavery as a “moral and political evil” was actually a letter primarily devoted to denouncing abolitionism as a doctrine and Northern abolitionists as a group). So was John Taylor of Caroline. So was Jefferson, at times, although at other times he made hypocritical gestures towards a more anti-slavery position. It is either pure ignorance, pure folly, or pure chicanery to try to represent this position (which recognizes no moral obligation to stop enslaving actually existing slaves, and which explicitly prefers the indefinite continuation of slavery unless and until all black people could be ethnically cleansed from their life-long homes in the American South and forced to foreign colonies in Africa) as an anti-slavery position. Real abolitionists in the 19th century were quite familiar with this position (since it was the official position of the American Colonization Society, an organization of which John Taylor of Caroline was an early supporter and officer), and they denounced it furiously. (See, for example, William Lloyd Garrison’s Thoughts on African Colonization.) As well they should have, since the position is, first, racist rubbish, and, second, quite clearly calculated to ease the consciences of squeamish slavers rather than to free those held in bondage. Those who sentimentally wished for slavery to end, somehow or another, in some far-off day which they perpetually deferred in the name of some other goal that justified their keeping slaves in the meantime — as, for example, with John Taylor of Caroline and his dreams of a Negerrein Virginia — no more count as anti-slavery for those idle remarks than George W. Bush counts as anti-war for having said (in his speech announcing the Iraq war) that war is terrible and he longs to live in peace.
This is the necessary context — that is, the context of John Taylor of Caroline’s actual thoughts about the nature of the “evil” in question and what if anything ought to be done to “alleviate it” (short of “wholly cur[ing]” it), and what all that actually meant in practice for the many black people whose slave-labor he himself was living off of while he wrote those lines — that your isolated use of that single quotation, and your frankly outrageous attempt to paint this active slaver as being anti-slavery, omits.
As for your accusations of plagiarism, I thank you for quoting the passages that you claim to have “caught” me plagiarizing. I’ll be happy to let the reader judge whether what I wrote could fairly be described as “plagiarizing” either of the other passages that you mention here.
