That's a very heavy charge, 'Dees. You're asserting that the Yankee abolitionists essentially wanted emancipation of the black slaves so that they could murder white Southerners ... that they were advocating genocide at one remove. Wow. I've never seen that one before.
It's worth noting that a lot of abolitionists came out of New England seminaries -- but this would be the ultimate in hellfire-and-damnation from the New England pulpit. What, exactly, did the Southerners do that pissed these people off so royally?
Is there a quote anywhere, about that genocidal rage you attribute to them, where we can read the lethal wish in the original? Or have you read someone who attributed that motive to them?
It is not to be disguised, that a war has broken out between the North and the South. -- Political and commercial men are industriously striving to restore peace; but the peace, which they would effect, is superficial, false, and temporary. True, permanent peace can never be restored, until slavery, the occasion of the war, has ceased. The sword, which is now drawn, will never be returned to its scabbard, until victory, entire, decisive victory, is ours or theirs; not, until that broad and deep and damning stain on our country's escutcheon is clean washed out -- that plague spot on our country's honor gone forever; -- or, until slavery has riveted anew her present chains, and brought our heads also to bow beneath her withering power. It is idle -- it is criminal, to hope for the restoration of the peace, on any other condition. Gerrit Smith to the New York Anti-Slavery Society Presbyterian Church in Peterboro NY, October 21, 1835
Note that Smith said this in 1835. These people actually believed they were at war with the South that early. Read some of the works of Garrison in his whackjob newspaper, The Liberator. He and his fellow lunatics were unable to restrain themselves from fantasizing about slaughter and subjugation.
"I do not believe in battles ending this war. You may plant a fort in every district of the South, you may take possession of her capitals and hold them with your armies, but you have not begun to subdue her people. I know it means something like absolute barbarian conquest, I allow it, but I do not believe that there will be any peace until 347,000 men of the South are either hanged or exiled." Wendell Phillips, at the pulpit of Henry Ward Beecher's Church
"If I had the power, I would arm every wolf, panther, catamount and bear in the mountains of America, every crocodile in the swamps of Florida, every negro in the South, every devil in hell, clothe them in the uniform of the Federal army and turn them loose on the rebels of the South and exterminate every man, woman and child south of the Mason and Dixon's line. I would like to see negro troops, under the command of Butler, crowd every rebel into the Gulf of Mexico, and drown them as the devil did the hogs in the Sea of Galilee." "Parson" Brownlow, ex-governor of Tennessee
These last two are wartime speeches, but you can read similar sentiments in the prewar speeches of these lunatics in any collection of their prose. Look into some of Beecher's sermons and the writings in the abolitionist broadsheets of the day. It's surprising to me that you don't already know about the radicals.
