The Kansas-Nebraska Act was passed in 1854, and according to this act, slavery was permitted throughout Kansas and Nebraska, and these two states were supposed to be admitted into the Union. However, there were many riots, both from pro-slavery movement, and anti-slavery movement, so the act didn't come into effect.
I would definitely be against the Act because, like I said, it allowed slavery in those two states. Slavery is illegal - you cannot be the owner of any person because we are all people. And given that according to this Act, that is exactly what you could do in those states, I would have definitely opposed it then, and now.
