Okay, so Southern Democrats were who supported slavery, and "In the 19th century, Southern Democrats comprised whites in the South who believed in Jeffersonian democracy." In case you don't know what the Jeffersonian democracy is, "The Jeffersonians were deeply committed to American republicanism, which meant opposition to aristocracy of any form, opposition to corruption, insistence on virtue, with a priority for the "yeoman farmer", "planters", and the "plain folk". They were antagonistic to the aristocratic elitism of merchants, bankers and manufacturers, distrusted factory workers, and were on the watch for supporters of the dreaded British system of government. Jeffersonian democracy persisted as an element of the Democratic Party into the early 20th century, as exemplified by the rise of Jacksonian democracy and the three presidential candidacies of William Jennings Bryan. Its themes continue to echo in the 21st century, particularly among the Libertarian and Republican parties."
Democrats and Libertarians are different, by the way. Libertarians are described as sort of a mix of both parties. So, in a way, the ancestors of the modern-day Republican party supported slavery more than the ancestors of the modern-day democratic party. And while some of the slaves were sold as punishment, the majority of them were kidnapped, then shipped off to America, where they went to the plantations in the South, where they were owned by.... well, democrats, but it's been said that "Since then, the only vestige of that era left on the party is the name “Democrats”. The party itself bears no resemblance at all to the party of that era." So, none of your arguments are valid. And I am moraley opposed to slavery, and I am highly insulted that you think me-a twelve year old-would have already chosen a party. I am not so close-minded as some (not you, just some people I know) as to make a decision this early in my youth. And it's not bad the USA has immigration laws, it's bad that we are fighting ALL illegal immigrants, instead of the ones that actually pose a threat, as well as the legal immigrants that pose a threat. But you can have your opinion.
