"In almost every nation and every clime, Acton writes frankly in his lecture The Civil War In America,
the time has come for the extinction of servitude. The same problem has sooner or later been forced on many governments, and all have bestowed on it their greatest legislative skill, lest in healing the evils of forced but certain labour, they should produce incurable evils of another kind. They attempted at least to moderate the effects of sudden unconditional change, to save those whom they despoiled from ruin, and those whom they liberated from destitution. But in the United States no such design seems to have presided over the work of emancipation. It has been an act of war, not of statesmanship or humanity. They have treated the slave-owner as an enemy, and have used the slave as an instrument for his destruction."
That's right Mr. Acton, the opponents of slavery did treat the slave-owner as an enemy, just as they should be.
We all know the scam that conservatism is.
