I finally looked for the 'real' Climate Scientists I know of that registered skepticism about the science at that time. Most are not mentioned but Richard Lindzen is, but also given credit as being a 'real' scientist. It seems to indicated that the scientists you accuse of being biased, are at least begrudgingly objective.
To me, if your thesis is that scientists are 'biased' I say "ok, humans are biased - sorry Waldo" and I also say "enough scientists in a culture that values objectivity will provide a space to discuss reasonable doubt". They were discussing whether reasonable doubt was in fact being registered. There is such a thing as unreasonable doubt.
And with regards to Lindzen, a real climate scientist who had doubts, the leaked emails say:
"As token skeptic there is Dick Lindzen—but at least he is a smart guy and he does listen."
