take it you don’t know what Lincoln said about slavery then and why he went to war, psstt it was not slavery... a little speech about preserving the union and not freeing slaves.
I’ll let you search it through Bing etc
It was the South that initiated the war. And their rebellion was motivated by defense of slavery.
I do indeed know what Lincoln said.
Lincoln was a complicated man and a politicion. Contrary to the Geico commercial, he might have said one thing in the south and another for northern consumption. Regardless, slavery was an underlying cause of the war, not the only cause.
An eyewitness report of Lincoln visiting freed slaves in Federally occupied Richmond indicated they (the freed slaves) looked upon Lincoln as an emancipator. That's good enough for me.
