To abort or not to abort

[Mudhammam]

One thing that troubles me about pro-lifers (and I do take their arguments seriously) is this idea that a fetus has personhood rights on the basis of its potential to be a sentient being or in virtue of its human DNA. That's all fine but it seems like if one is going to value the status of a fetus, which is presumably not conscious or aware (question: is it perceptive? I don't see how) then pro-lifers should be adamantly against the way other conscious and sentient animals are treated.
