I'm saying the north made slavery their battle call only after other factors motivated them. The proof they didn't give two shits about black folk were the jim crow laws they allowed the southern states to adopt during reconstruction.
Edit: ignorance of the truth will not change the reality of it. Sure there were many in the north who were against slavery. As there were some in the south at the time who were against it. When the south started trying to purchase manufacturing equipment from Britain the north imposed restrictions on its import in the form of... You guessed it tariffs. This caused much back and forth and when the north needed a reason they had a just one in the form of slavery. Somehow people seem to miss this with our dumbed down education system. They make slavery the only reason and forget how politics works. Looking at our current shit show why do you think anything has changed in all that time?
Eduacate yourself and quit repeating nonsense

I could go on but if you can't be bothered to learn the truth of then how could you ever hope to understand the situation today.
