No, it isn’t. Often, when people want to avoid uncomfortable questions, they resort to sleight of hand. Your statement is a perfect example of that.
curlcoat specifically stated that only the mother has the right to decide when the organism in question becomes human. (Purely for the sake of argument, let us assume that the unborn is indeed something that must eventually become human, rather than being human from the onset.) To examine the validity of this premise – namely, that one can not decide this matter for other people – I specifically asked,
"What if a woman decides that it doesn’t become human until two years of age? Or three? Or thirteen?
For that matter, what about people who believed that blacks weren’t fully human? Should we object if they were to declare, ‘You have no right to decide this matter for me’?"
The reasoning behind these questions has been correctly discerned and eloquently expressed by both Stratocaster and the pro-choicer, cosmodan.
Now you choose to summarize my response as “What if the person is black?” As you know full well though, that was only one tiny portion of my line of inquiry, and your particular phrasing edits out its entire rationale. It’s a convenient way to avoid uncomfortable questions, but convenience and accuracy aren’t by no means the same thing.
