Also, I'll request that we both have the common courtesy to use the accepted monikers each side has chosen. Pro-life isn't a wildly inappropriate, meaningless, or deceptively dishonest appellation. It is anyone like-minded, is acting in bad faith; that the goal isn't really the protection of life, but the removal of the choices of women.
I don't think that rejecting the label "pro-life" necessarily implies that the person is acting in bad faith.
The label implies that a person's stance on abortion is informed by a generally "pro-life" view of the world: that the person's values and actions show a high regard for human life in general. This might be true for some people who are against legal abortion, but not across the board.
We frequently see people who are anti-abortion but are "anti-life" in all sorts of ways, e.g. by being pro-war. The anti-abortion movement is a mix of people who are pro- and anti-life, so it doesn't make sense to apply the label "pro-life" to the whole movement... regardless of your particular reasons for opposing abortion.
I think that the term "anti-abortion" is even often inaccurate, since the "anti-abortion" movement includes many people who support causes that tend to increase unwanted pregnancy (e.g. abstinence only sex ed or reduced availability of contraception). Also, in the US, it generally doesn't push causes that would encourage the women who might seek abortions not to abort (e.g. job-protected maternity leave on par with most of the developed world, or ensuring that the health care costs of having a baby won't bankrupt a new mother).
I think that last point is the most telling. I understand that many religions have objections to contraception, but I can't think of any mainstream religion that objects to treating new mothers with decency and respect.
At least in North America, the movement against the legalization of abortion has not generally advocated measures that would give pregnant women in the position to abort good choices besides abortion. In fact, it's been often the case that some members of this movement have actively opposed these measures.
The day I see a march or a petition demanding decent care and benefits for new mothers as an anti-abortion strategy is the day I'll stop calling the movement anti-choice.
Edit: trying to deny women the ability to get a legal abortion IS anti-choice. It may be - but is not necessarily - part of an anti-abortion position. It may be - but is not necessarily - part of a "pro-life" position. The term "anti-choice" doesn't imply that you aren't "pro-life"; it just acknowledges that the term "pro-life" is baggage-laden and implies things about the person or movement it's applied to that may or may not be true.
