Religion should play no role in debate on abortion

A close friend of mine told me a story about something which happened in their child’s science class.

When a child asked about God’s role vis-à-vis science, the teacher responded: “We will have no talk of mythical sky creatures in my class.”

If God should have no role in a science classroom, then should there be no role for said mythical sky creatures in political discussion, particularly those relating to issues as serious as abortion?
