Are there any pro-lifers who are NOT religious?

I am not particularly religious, I believe there could be a higher power , but I do question some aspects of organized religion. I also believe all life is holy . And I wonder, if it's not a baby, why do you need an abortion ? I knew a woman who had an abortion because the pregnancy would have interfered with a cruise she had planned !!! A lot of abortions are performed because of that kind of shallowness !
