These pro-life groups continue to use wording that pro-choice/pro-abortion groups have chosen. In my view, the impression being sought to convey is the proposal has to do with the abolition of some archaic legalism. Who would say no to this? It also avoids any unpleasant discussion of the reality.
To be fair, pro-life groups are repulsed by the taking of (unborn) human life. Helping their opposite numbers is not intentional. However, the “opposite numbers” are quite happy with the arrangement, whereby the real subject is not mentioned by either party. That way, we can have a nice, civilised, polite discussion, and nobody gets hurt. Well, except for those with no voice.
