I have said that President Lincoln was a white man, and shared the prejudices common to his countrymen towards the colored race. Looking back to his times and to the condition of his country, we are compelled to admit that this unfriendly feeling on his part may be safely set down as one element of his wonderful success in organizing the loyal American people for the tremendous conflict before them, and bringing them safely through that conflict. His great mission was to accomplish two things: first, to save his country from dismemberment and ruin; and, second, to free his country from the great crime of slavery. To do one or the other, or both, he must have the earnest sympathy and the powerful cooperation of his loyal fellow-countrymen. Without this primary and essential condition to success his efforts must have been vain and utterly fruitless. Had he put the abolition of slavery before the salvation of the Union, he would have inevitably driven from him a powerful class of the American people and rendered resistance to rebellion impossible. Viewed from the genuine abolition ground, Mr. Lincoln seemed tardy, cold, dull, and indifferent; but measuring him by the sentiment of his country, a sentiment he was bound as a statesman to consult, he was swift, zealous, radical, and determined.
The Ashbrook Center for Public Affairs in Ashland, Ohio will probably be surprised to learn that they are neoconfederates. As for "clipping Douglass off mid sentence" I stopped at a paragraph, as did you. The entire speech is available at the link I posted.
