What is Reddit's opinion of The Doctrine of Balaam?

From 3.5 billion Reddit comments

The description from the Amazon page isn't incredibly helpful:

>For decades the Church of Jesus Christ has been tossed to and fro during our abortion holocaust. For a variety of reasons her pulpits have largely been silent. The lack of biblical instruction, discipleship and discipline has weakened the understanding of professing Christian congregations with catastrophic effects. Nearly all of the education, training, and work done in this area has been outsourced to the secular prolife establishment. We are now at a point when pastors and leadership and average professing Christians assume that the secular prolife establishment doctrine and practice is the Christian position. The Doctrine of Balaam seeks to examine these doctrines that have crept into the church against scripture and the light of nature and will ask the Christian to stand with their Lord, regardless of circumstance and with His mind, say with Him “Thus says the Lord.”

I usually read the reviews to get a better view. Excerpts from the first review:

>From the beginning it should be noted that the book itself carries a pastoral tone. While Pastor Cali examines and dismantles the secular Pro-Life movement, he does so never attacking the people. Rather he attacks the unbiblical ideas, systems, traditions, and even sins, that facilitate and further the ideas, policies, and actions, the movement produces.
No staunch Pro-Lifer should come away from this book feeling attacked, but rather challenged and convicted. It should drive people to their Bible's and their knees...
I firmly believe no Christian could read this book and give a biblical refutation of it. I further believe no secular Pro-Life movement participant or leader could refute the sound logic that flows from the biblical truths contained in the book either. It is short, powerful, and I dare say irrefutable, in light of scripture and sound reason.

So it seems to be a book that mostly attacks/criticizes a "secular pro-life" stance, in favor of a "biblical" pro-life stance. I'm curious and confused about why this is a useful thing to do.
