I can see the argument for being pro-life.

Nobody wants abortions.

But if you are pro-life you must also have a consistent life ethic:

… an ideology that opposes abortion, capital punishment, assisted suicide, and euthanasia.

Adherents are opposed, at the very least, to unjust war, while some adherents also profess pacifism, or opposition to all war.

The term was popularized in 1983 by the Catholic Cardinal Joseph Bernardin to express an ideology based on the premise that all human life is sacred and should be protected by law. … 

In the States, many who claim to be pro-life also support the death penalty, support the right of untrained neighbours to own weapons of war.

They support wasting any amount of money on the military while denying basic health care and education to the young women who might consider having an abortion.

They are pro-birth, not pro-life.  Once the baby is born they no longer care what happens to the child.
