Uhh, given that anti-abortion politics goes hand-in-hand with opposition to any sort of public benefits for healthcare, its hard to take seriously the notion that pro-life is anything more than pro-birth
For anyone with a stoic, scientific understanding there is a point where both beings become equal during gestation. This probably occurs somewhere around 20 weeks. However, <2% of abortions are had after this time. It is a necessary evil that nobody should feel responsible for unless they are directly involved (even then, the best choice out of two bad options).
No, it's pro-personal responsibility and pro not killing children.
The same thing goes for benefits programs -- nobody wants kids to be starving in the streets, but we would rather that people exercise personal responsibility in taking care of their own kids rather than expecting the rest of us to pay for their care.
Those positions are not opposed, and there's a lot of nuance in the whole welfare debate, it's not all or nothing.
