Which argument was that, pal?
may i also remind you of a favorite saying of one of my grad school profs, "things in history are simple only to simpletons".
TWBTS was MAINLY a REBELLION of the citizens of the southland for FREEDOM from the ELITISTS of the northeast. 90+% of southerners owned NO slaves and were singularly UNWILLING to fight/bleed/die for "some rich guy's right to keep his slaves". (in the case of MY family, EVERY male of "military age" fought for the south; about HALF of them died for THE TRUE CAUSE. further our family was "dirt poor" AmerIndians & could NOT have afforded a single slave, had any of them wanted to buy one!!!)
the VAST majority of southern soldiers/sailors/marines fought for HOME defense,their STATE,for FREEDOM for the south & FOR EACH OTHER. (the reasons that southerners fought were NO different than the reasons that motivated their grandfathers, who fought against the tyranny of George III.)
