Q: Should this article's title be pro-life movement?
A: No. Wikipedia does not use euphemisms. The term "pro-life" is a branding or marketing device and does not reflect the sole focus of the movement, which is opposition to abortion. The fact that the two sides officially call themselves "pro-life" and "pro-choice" is not a reason for Wikipedia to prefer those terms, since neither is neutral, nor accurately describes their positions.
This was discussed at length in June 2018, when the titles of both articles were changed to neutral titles: pro-life movement --> anti-abortion movement and pro-choice movement --> abortion-rights movement. The former group of people is unambiguously opposed to abortion, so there's nothing misleading about the name. It's a neutral name, which should not offend anyone who truly believes that abortion is wrong.
Additionally, the term pro-life is a political spin term that does not necessarily reflect reality. The philosophy which opposes both abortion and the death penalty, and which supports access to healthcare and other life-sustaining measures, is termed consistent life ethic.
Similarly, pro-choice is a political spin, because it disguises the fact that people are talking about abortion. They are not talking about your right to vote in an election. The most neutral term (according to consensus in 2018) is the abortion-rights movement, because its advocates unambiguously believe that a woman has a right to have an abortion, subject only to the usual restrictions based on trimester. It would be wrong to call it a pro-abortion movement, since typically the spokespeople for the movement primarily advocate for female bodily autonomy and a hierarchy of measures beginning with widely available contraception and high quality sex education, with abortion as a final option in the case of unwanted pregnancy.
