You might be able to reconcile an anti-abortion position with a pro-death position when it comes to capital punishment. Clearly in the States a lot of people seem to manage to do that - though it's not quite so common in other places, where opposition to abortion tends to go hand in hand with opposition to the death penalty (though it doesn't apply the other way)- but calling that being "pro-life" is surely a step too far.

I suppose you might find someone who eats chicken claiming to be a vegetarian on the grounds that they don't eat beef.
