There is risk with everything in life. If someone is having sex, regardless of condom use, birth control use, vasectomy, etc., they are accepting the risk of an unplanned pregnancy.

Why is it that we push for the killing of unborn persons instead of taking responsibility for the consequences of one's actions?

> accepting the risk of an unplanned pregnancy.

No, they're accepting the risk of having an abortion.

That's per year, not per instance. So it's really quite high.
