The Church does not disagree, but the reverse is also true, how can you claim to value fetal life if you are dismissive of it at other stages?
Being ‘anti-abortion’ is not necessarily the same thing as being ‘pro-life’ in the Catholic sense. Look at how we, the laity, are told to view “the right to life”:
vatican.va/holy_father/john_paul_ii/apost_exhortations/documents/hf_jp-ii_exh_30121988_christifideles-laici_en.html
I hear the first two paragraphs quoted a lot, with the assumption that “right to life” is a synomym for anti-abortion. But the third paragraph tells us what the phrase means to the Church. “Right to life” includes abortion and euthanasia, but also slavery, torture, and even deportation.
Viewed this way, the original question should probably be reprhased to ‘why aren’t more priests spending more time on one particular aspect of Church teaching?’
The Vatican’s advice on voting is as good an answer as any:
Pastors are responsbile for sheparding and nurturing us in Catholic life. In other words, they are supposed to help us develop proper Christian conciences. Such a concience would see that opposing abortion and, say, human trafficing, are both applications of our same teaching, a proper understanding of the Human Person.
