If being against abortion isn't a religious issue then why do so called pro lifers cite their faith as a reason to oppose abortion?

I have seen them argue that being against abortion isn't about religion and yet the majority of people who are supposedly pro life cite their faith as the reason or one of the reasons why they oppose pro choice. It's like they are willing to lie and enforce any means to claim the moral high ground that they never had.
