Drawing the lines

On the one hand, Abolish Human Abortion refuses to cooperate with Catholic prolifers on theological grounds.

On the other hand, AHA views itself as heir to the anti-slavery theorists and activists. Yet abolitionists like Louisa May Alcott, Susan B. Anthony, Ralph Waldo Emerson, William Lloyd Garrison, Angelina Grimké, Thomas Paine, Theodore Parker, Jean-Jacques Rousseau, Henry David Thoreau, and Theodore Weld were by no means theologically orthodox. 

By the same token, the men who effectively abolished slavery in America (e.g. Lincoln, Sherman, Grant) were by no means theologically orthodox. 

Ironically, AHA's position is the mirror image of the Confederate theologians who opposed the abolitionists because they were heterodox.
