Oh, I agree that that term "anti-abortion" is focused specifically on the target issue.

I also agree that the term abortion does not startle those already engaged in the debate. However, I think there is a perception that the word itself gets people stirred up and upset, and I suspect that to some more limited degree, that is true.

Startlement is not the only way a word can garner an emotional reaction.

I do agree that the term "pro-life" benefits strongly from the constellation of related ideas implied in the word "life".
