The term “pro-life” has been stretched pretty thin by those who support certain things. Those things in themselves aren’t bad, but it does reduce the term to something less than what it is.
Working to help the mother with maternity leave is a very important duty and and a noble one, and it is part of the corporal works of mercy.
However, consider St. John Paul II’s words;
"Above all, the common outcry, which is justly made on behalf of human rights – for example, the right to health, to home, to work, to family, to culture—is false and illusory if the right to life, the most basic and fundamental right and the condition for all other personal rights, is not defended with maximum determination.”
I’m not prepared to call this a pro-life issue. A good responsibility to take an one we should be doing, but it’s not quite the same.
When it comes to legislation, Catholics are obligated to side with law that works in favor of protecting life; ie voting against abortion, etc. However, Catholics aren’t obligated to vote for legislation that demands all businesses set up a specific amount of time for maternity leave. However, it is still important to also work toward different means to assist these parents.
To acknowledge the term “pro-life” meaning support of the life itself and the dignity of it by working against killing of life, from womb to tomb, doesn’t make you merely pro-birth – this is a term used to defeat any argument that divides up scenarios. “If you do not support the decriminalization of all drugs, then you are just pro-birth because you don’t care about families staying together.”
There has to be a difference, and it’s not a litmus test. Those that see the value of all matters, even prudential subjects, aren’t now by default demeaning or making light of abortion. And likewise, those who distinguish the hierarchy of direct killing of life vs. subjects that are difficult on others like joblessness are now not by default simply “pro-birth.” We need to be more honest when we dissect these things.
That said, if someone supports something like legislation making maternity leave more accessible while turning away from opposing abortion or euthanasia, this is badly prioritized. This is why St. John Paul II made that statement above – the fundamental right to life cannot be undermined, even if the rationale is to protect other good things. One is more basic and important than the other.
