He's pointed out all the same lies and revisionism you always engage in and then your resort to ad hominems when your arguments are refuted and admittedly I do too but only after my patience is reaching the limit. I've stated previously the facts as to the South secession, it's first use military engagement and it's invasion of Maryland and Pennsylvania. Closing the door on this for now.
You are attempting to revise history here. Prior to the 1980s even most Academics did not subscribe to the All About Slavery myth. That was a bunch of 1960s Leftists who really started pushing that in the 1980s during their long march through the institutions. Prior to that, most would have said either that it was a mix of reasons OR would have agreed with Charles Beard that the war was really all about the money. You clearly don't know the historiography.
You're trying to rewrite 1861 so as to whitewash the fact that the federal government violated the Constitution and the Founder's principles in order to fight a war for money and empire and to impose a government upon people who did not consent to it. I've pointed out his lies and propaganda he always resorts to as well as his childish namecalling of Chief Justice Taney and his attempts to pretend Chaney alone decided Dred Scott instead of the entire SCOTUS whenever his BS claims are refuted by the facts. I've pointed out to you several times that the Southern states were more than happy to leave in peace. It was Lincoln who insisted on war and who took the acts of aggression that started the war - deliberately. I'll keep repeating as many times as are necessary for you to grasp that.
