Let's look at the whole quote. In context, for a change.
" In doing this there needs to be no bloodshed or violence, and there shall be none unless it be forced upon the national authority. The power confided to me will be used to hold, occupy, and possess the property and places belonging to the Government and to collect the duties and imposts; but beyond what may be necessary for these objects, there will be no invasion, no using of force against or among the people anywhere. Where hostility to the United States in any interior locality shall be so great and universal as to prevent competent resident citizens from holding the Federal offices, there will be no attempt to force obnoxious strangers among the people for that object. While the strict legal right may exist in the Government to enforce the exercise of these offices, the attempt to do so would be so irritating and so nearly impracticable withal that I deem it better to forego for the time the uses of such offices.
The mails, unless repelled, will continue to be furnished in all parts of the Union. So far as possible the people everywhere shall have that sense of perfect security which is most favorable to calm thought and reflection. The course here indicated will be followed unless current events and experience shall show a modification or change to be proper, and in every case and exigency my best discretion will be exercised, according to circumstances actually existing and with a view and a hope of a peaceful solution of the national troubles and the restoration of fraternal sympathies and affections."
Lincoln is speaking of the duties of the government. To hold on to government property. To fill government posts and deliver the mail and, yes, collect tariffs. Yet you latch on to one item and screech, "He's threatening invasion!!!" while ignoring the pledge that force would not be used unless forced upon the government.
Five weeks later, on April 12, Fort Sumter, a tariff collection point in Charleston Harbor, was bombarded by the Confederates.
Complete crap, except for the bombardment part, of course. Fort Sumter was an army post, not a 'tariff collection point'. The customs house in Charleston was on East Bay Street. Not one dollar of tariff was ever collected at Sumter and not a single customs official ever set foot in the fort. So how was it a 'tariff collection point'?
No one was hurt or killed, and Lincoln later revealed that he manipulated the Confederates into firing the first shot, which helped generate war fever in the North.
So your arguement is that Jefferson Davis was too stupid to see through Lincoln's plot and fell right into is trap? In spite of the warnings that his cabinet gave him? No wonder the south lost with a leader like that!
With slavery, Lincoln was conciliatory. In his first inaugural address, he said he had no intention of disturbing slavery, and he appealed to all his past speeches to any who may have doubted him. Even if he did, he said, it would be unconstitutional to do so.
And by that time seven southern states had entered into a rebellion to protect slavery.
I give up. You simply will not believe anything other than the official government endorsed cause for the War of Northern Agression. They would never lie to you, right?
