Gee...hidden agenda, anyone?
abortion, n. abortiveness, miscarriage, prematurity, immaturity. See NON-PREPARATION.
I double-checked it by looking in my hardbound edition of Roget's Thesaurus:
Nothing about abominations. Now, apparently an archaic meaning found in the Oxford something something says something about "misshapen or miscarried offspring"...nonetheless, though, to only include those meanings in the thesaurus seems questionable to me.
Note that I'm not bringing into this whether I'm pro-choice or pro-life or whatever they call those these days—I don't claim either affiliation, and don't plan on claiming one anytime soon.
