Picaro is guilty of false equivalency with the photos suggesting the Union's black units were like the SS adjunct units.
I suggested no such thing; somebody posted a pic of black Union soldiers as if that showed the Union was 'mutli-racial', I provided an excellent example of why that doesn't say much about northern realities and racism in the north, any more than posting pics of blacks in Hitler's armies shows that Nazis were not racist.
New York blacks formed two or three regiments of volunteers in 1861; they were denied the approval to serve in the Union army until later in the war, when the north was too desperate for manpower to fill its lines that they finally allowed blacks to serve as soldiers.
It's not true, it's deliberately a lie, and it reveals a real hatred of people of color.
You're lying here, of course. You just deliberately distort things you don't personally like, like most northern apologists hate anything that tarnishes their self-serving fantasies re the Civil War. Like the historical fact that they were as corrupt and amoral as everybody else on the planet, and nothing noble or 'special'. We have their conduct and actions after the war as yet more shining examples of their pocket stuffing self-interests, the Grant administration and 'Reconstruction', along with a clear record of Republican priorities when they occupied Congress with no opposition and were free to pass all their pet bills. We know for an absolute fact slavery wasn't anywhere near the top of their list.
