And yet, pro-choice individuals seem to object to referring to the individual in question as a baby - a much stronger analogy - far more strongly than they do to calling them a "human" or even "human life".

Hmm.

With all due (and considerable - I'm something of a fan of yours) respect; how many pro-lifers do you think are actually reasoning in the manner you describe?

I sure don't know. I may be "pro-life", but I'm conscious that I am in no sense a typical pro-lifer. Many of them seem to rely on "natural law", which is childishly easy to deconstruct, and to object to contraception, homosexuality or other practices I do not object to.

But selection effects well in mind, it seems to me I've heard this argument many times before - and always in the mouths of pro-choice individuals making this argument, not pro-lifers describing or justifying the position they actually hold.
