In a recent thread, I contrasted the OP’s use of the term “Pro-Life” with “pro-abortion”. This provoked something of a reaction. The OP took offense, saying “If they aren’t going to show us the courtesy of using the term we prefer” etc. and another poster called it “discourteous”. In a current Pit thread, an (apparent) pro-lifer objected to the term anti-abortion saying “The pro-choicers do not like to be called pro-abortion, and the pro-lifers do not like to called anti-abortioners”. Without getting into the exact specifics of these cases, I have a general point about labels and a specific discussion of the ones that apply to the abortion issue.
It would seem to me that there is a clear distinction to be made between groups that have true names on the one hand, and descriptions of a group’s characteristic or positions on the other. In the case of named groups, the names are used as, well, names. Use of names should be purely a matter of courtesy and the holders of these names rule the day. Just as you would not address someone who wants to be called William as Bill, so too you would not call a group by a name that they dislike. If Chinese people wanted to be called Igharis (or whatever), courtesy would require that one call them by this name.
In the case of holders of a political position, the name is not a name, it is a direct description of the group. The words chosen to describe the group are those that are believed to best fit the group. No one has a right to demand that their position on issues be described in any given way. There is no courtesy issue involved here at all, as far as I can see, and suggestions otherwise are, I think, misguided.
This does not mean that members of a group cannot demand that they be referred to in a certain way. Merely that the grounds are different. In the example given, many people who oppose restrictions on abortions prefer the term “pro-choice” over pro-abortions. There is a justification for this, in that many such people feel that the term pro-abortion implies that they desire more abortions, while in reality they merely favor having that choice available. This is legitimate grounds for such a demand (in the thread discussed, one poster did announce a preference for “pro-choice” on such grounds). But it is true only to the extent that the positions actually are more accurately described thusly.
In the specific case of abortion, I would think that pro-choice and pro-abortion differ only marginally, if at all. Reason being that I don’t think anyone actually interprets the term pro-abortion to mean that the person favors an increase in abortions. There are numerous examples of this in the political lexicography. A person who is pro death penalty is not in favor of it in every instance - most people would probably rather keep the death penalty available but rare (IOW, keep the need for it down) exactly as is the case with pro-choicers. But everyone understands that the crux of the issue regarding the DP is whether the death penalty should be given in certain instances, and the “pro” and “anti” are correctly understood in this context. So too, the term pro-abortion is correctly understood to mean that the person is on the pro side of what happens to be the issue in this case - should abortion be legal. I think the objections to the term pro-abortion are in reality a political ploy - a means of shifting the debate away from the fetus and towards the woman - this is the winning part of the debate for the “pro” side.
The term pro-life is even worse. Everyone is pro-life. The term anti-abortion is a far better descriptive of the actual positions espoused by this side of the debate. I am convinced that the term pro-life is purely a PR gimmick and has no legitimate purpose.
Having said all that, I don’t think there is a purpose in needlessly aggravating people who are convinced that all of the above is true (misguided as they may be :D). So the preceding is directed at those who would demand this or that term for themselves, rather than at those planning to address a group by a name they despise.
