ABC’s attempt is to put ALL Christians in a bad light, so anyone considering turning to God, will not. There is good and evil. God and satan. They are doing satans work.
I suspect anyone who makes an argument that ascribes motive to another. It is rarely accurate.
That said, are you familiar with the work in question at all, or are you merely speculating and/or projecting? I, myself, have read the book, which I found to be quite good. People like the characters do exist, and yes, they make for good reading.
