Do you believe slavery was a moral sin?
Yeah. And the nation paid for it dearly in blood and treasure. Almost unto the death of the republic.
Are you trying to use the original sin of the founders in not ending that vile practice to justify the the deaths of the tens of millions of little children who have been killed by the abortionists, with Mitt Romney's full support? Or what? Really, what's your point?
