most people feel so strongly about slavery because everyone has their own beliefs. one reason is most people that are black are wanting to go against slavery because that's THEIR race. also some people think it was good to have slaves because it could bring them good things. a lot of slave owners wanted slaves because they wouldn't have to do things themselves. some people are so against slavery that they helped the slaves and risked their lives trying to get the slaves to safety.. but their is also a lot of racist people that want to think slaves were good and such.
