If you're going to respond to this post, please respond to the other points I've made. Especially in regards to FDR, Coolidge, Wilson, and Douglass.
Also, Sweden didn't fully outlaw slavery until the mid 1800s (be careful where you get your evidence). Japan enslaved millions of people during WW2. Denmark and Norway still had slavery until the 1800s. Portugal still maintained slavery in Africa. Many of the glorious freedom nations you have just mentioned actually continued slavery in their colonies.
