And if you've got a problem with "liberals," then take a look at the history of the U.S. Liberals wrecked the slave system, and also brought women the vote.
Are you, "guest," against those actions?
It's probably not a good idea to use terms like "liberal" and "conservative" when talking about the anti-slavery movement in the US. Liberalism as it was used back then referred to economic decentralization originally promoted by Jefferson and embraced by the slave states because it protected the "rights" of slave holders (Jefferson was himself a slave holder). The anti-slavery party was the Republican Party, formed in 1854 around the issue of slavery. The Republicans might be called 'progressive' in the sense that industrial capitalism can be said to represent progress over slavery, but they certainly weren't progressive or liberal in the sense that we mean those terms today. The only political group at the time which supported government backed social welfare programs was the socialists who were then, as they are now in the U.S. a marginal political force.
The Republicans were quite a diverse group. They included "radical" Republicans who were abolitionists, usually based on moral or religious grounds. Industrial capitalists who were anti-slavery because their economic interests were in direct conflict with the economic interests of the slave holding class. And free laborers and farmers who opposed slavery because it cheapened the value of their labor in the labor market. The latter were often deeply racist and their opposition to slavery was primarily economic like the industrialists rather than moral like the abolitionists. Many free labor groups, Catholics for example were democrats and pro-slavery because they were an oppressed minority in the predominantly Protestant north and made common cause with the pro-slavery democratic party out of political expediency.
So it's kind of overly simplistic to use "liberal" and "conservative" to describe that situation.
