Very interesting, I was wondering how you came to this conclusion, if I might ask?
About ghandi or the northern racism?
Well if you look at the writings of the most predominant free soilers, the initial group that laid the foundation for the Republican Party abolitionist stance, they go into great detail on protectionist policies. The entire republican platform, at that time, was based on protectionist policies. They wanted extremely high tariffs rates and they favored big subsidies for steel and railroad. They attempted to subsidize canals, and roads which led to disaster. That, along with hardings death led to failure of the Whig party because Tyler came in and was extremely lasseiz fairs with his policies. The reconstruction of the Whigs included elements of the free soilers which adapted the party's platform and expanded it to the west.
If you read the writings and the platform of these people it's basically saying they wanted to expand the union west away from slave states, not because they hated slavery per se but because they wanted to have land where the laborers were not effected by competition with slaves. They also wanted non slave states to join the union because, at that time, slaves votes counted for 3/5 of a vote. They were worried that if western migration occurred with slavery the southern democrats would outvote the free soilers and it would lead to a policy that was lasseiz fare and non protectionist, I.e. Lower tariffs and less subsidies.
They also strongly opposed immigration, because immigrants brought in democratic votes because a majority of immigrants were pro lasseiz faire, this is easily explained because immigrants opposed strong national governments hence the fact that a majority of the immigrants moved here, at that time. It wasn't until later that the city and state governments started hiring Irish immigrants by the droves which later went to the expansion of immigrants becoming prostate
This is why the republicans and the free soilers created public schools, they thought Catholicism needed to be destroyed and said it was a moral sin against the union, if you will. So they started attempts to outlaw alcohol, and started teaching Protestant virtues in public schools. All were geared at eliminating the "libertarian" tradition of lasseiz faire, mainly because they were worried that these democrats would bring in policies that would eliminate the economic protection, as well as an assault on their religion or morality based on pietism and Protestantism.
These people attempted to outlaw alcohol in places like Kansas, because at that time the major political meeting ground for the democrat party was in taverns and bars, because a majority of these "libertarian" democrats who were immigrants brought their customs with them and one of the customs espexially with the Irish was to have all village social gatherings stem from he local bar. So the republicans were attempti to illegalize alcohol for the sole purpose of disrupting the democratic parties ability to have any political gathering space.
The main concern of the Republican Party was "free soil, free labor" modern historians view this as a thought of homestead act agreements to give out parcels of land to farm workers, and to relieve the slaves from slavery. The real reason for this "free soil, free labor" theory was that they wanted homestead laws to subsidize railroads, which later led to the extermination of the Native American population, and free labor was to end slavery from competition of the white labor market and restrict immigration to protect the "native born" white pietists and Protestants in their freedom of labor without outside competition.
Many liberal democrats switched to the Republican Party at first because of the "abolitionist" stance, and then when it became a nationalist party they reverted back to the democrat party. The democrats had a libertarian faction, and a strong state faction and the majority of the democrats that wanted Slavery to exist were doing so because they were worried that the economy of the south would crumble without slavery to the 50/60% tariff rates that were put into place.
Lincoln in his first inaugural address stated to the effect that he would not abolish slavery, that he was pro southern slavery, but he would enact higher tariffs and he wouldn't be afraid to use military force if there is any opposition. This lead to the civil war, and the confederate flag was used in the civil war to honor the southern history of military fighters, especially in Virginia. The northern states were enacti Jim Crow policies in Illinois, during Lincolns rise to politics, Lincoln also voted yes on the Chicago black code which would essentially criminalize all blacks from being citizens in Chicago, and Lincoln was in favor of an agenda to send all blacks to Africa after the civil war.
