I think from now on when someone tells me she's "pro-choice" I'll say, "Ah...you must be pro-slavery then!" When the speaker takes exception I will explain that "If you're pro-choice, you would have supported the Kansas-Nebraska Act that allowed territories the right to choose by popular vote whether to be slave or free. Because the freedom to choose is an absolutely essential right. Correct me if I'm wrong."
Can you just imagine the horrified look on a liberal's face when accused of supporting the politically incorrect choice of slavery? Liberals have absolutely no problem with the choice to kill black babies. What possible argument could they have against the choice to enslave black men, women, and children? If "choice" is a sacred sacrament, they must support the Kansas-Nebraska compromise. Hey, if you don't support slavery, don't buy a slave.
Somehow, I don't think that would fly among liberals. Keeping black slaves is horrible. Killing black babies is no problemo.
But then no one expects liberals to be consistent or logical. They make up the rules to match what they want to do today. And sex without complications requires access to child-killing. So stay away from Gettysurg, liberals. It is a monument to the results that come from supporting choice, i.e., civil war.
