slavery
"Slavery is like a resurgent disease in human affairs -- one which will never die unless a very real commitment is made to protect American freedoms. When we learn of continued slavery in the fields of Florida--and the deaths, rape, debt peonage, threats, and ruined lives that go with it -- we need to realize: this is a threat to our values and our way of life."
"Slavery is like that uncle that paid for my college, but also molested me"
"SLAVERY is like polio. Most westerners associate it with earlier, darker times in human history. Its eradication is a sign of human progress. And yet despite these perceptions slavery, like polio, has not in fact been eradicated "
Seems like this has been turned into a bit of a dichotomy. Slavery and the idea of states rights were both real. In discussions of the origin of the Civil War, these ideas are put forth as an either or proposition. What's a good analogy for this?
Can someone come up with something?
