No, I typically conclude that they are wrong. That this happens repeatedly, often on the same topics, has biased me to be highly skeptical of the arguments produced, that is true. But I do not simply declare the arguments wrong, I demonstrate that they are.
Like in this thread - I provided pretty clear evidence that they are wrong to claim Scadding proved vestigials are not real, or that they do not provide evidence for evolution.
In my experience (been doing this for about 20 years), I would say the overwhelming majority - "they" is shorthand.
What evidence does it actually present FOR 'Intelligent Design', as opposed to attacks on evolution?
Maybe your bias has you thinking this book is good because you want to believe that it is.
The author of that 2002 book is a medical doctor (supposedly), that also wrote such books as "God's Prescription For Healing: Five Divine Gifts of Healing" and "Come Unto Me: God's Call to Intimacy."
Maybe HIS bias has him finding God where God is not present?
