So what (according to you) would be an example of an organization that discusses the same topic that is not biased?
I'm not sure that there are any interest groups, on either side of this issue, that are not biased. They all have a big stake -- be it emotional, political, monetary, or all of the above -- in having the answer come out their way.
It is possible to approximate an unbiased assessment of homosexuality and so on, by means of rigorous sampling standards and analysis techniques, and a strict and dispassionate peer review process. That's not the case here.
And that's I was making: I was responding to the claim that the subject article was a "scientific" report, when it clearly is not that. The authors had a going-in opinion, and the purpose of the paper is to try to convince us that their opinion is correct.
