This does *not* parallel.
WHITE/BLACK SLAVERY:
A green apple and a red apple are both apples. While superficially
different they are functionally identical. There is a measure of
equivalence between these two apples, so judgements should be based on a
principle of equivalence.
FETAL ABORTION:
Consider a green apple and a green apple *seed*. In this case we are more
concerned with the relationship being *equitable* because by definition
there is no equivalence. An equitable judgement will not always favor the
fetus.
