A straw man argument is an exaggerated or caricatured version of your opponent's position. It generally consist of a false premise designed to be easily shot down, but has no actual relevance to the issue at hand.
When you said
"I can understand why atheists/non Christians may vier away from a conservative writing but is it helpful to have this black and white thinking? "Well, this is completely bias so all of this is completely false."
You mis-characterize my warning as an assertion that the paper is completely bias[ed] so all of this is completely false. I neither said nor implied any such thing. I said that her findings "
can be expected to present evidence and conclusions that have a distinct conservative bias." "Can be expected" does not equate with the definitive,"are." And my continuing remark about evidence does not encompass ALL evidence and conclusions. I intentionally phrased it so as to leave room for evidence and conclusions that do not have a conservative bias. Moreover, just because a paper is biased does not mean all or even any of its work is false; although, it is more likely than not that some of it will be.
And I didn't dismiss it, but rather warned against taking it at face value: be wary of what is presented and look for confirmation in other sources.
That's why I emphasized the value of peer review. It helps keep such bias to a minimum. Research that is not peer reviewed is always suspect. ALWAYS.
Good credentials go a long way in establishing credibility, but it's no secret that even well credentialed scholars have purposely mis-presented their research. Hence, even papers from the most famous researchers undergo peer review. Manning's paper was not.
