  ::Quoting the applicable section, if you give correct attribution is fair use, and not a violation of copyright.  I will have to try with my library card.  Good idea!  ::Since there are many traits that we do have yet associate specific genes to, that we have not identified a gene, or series of genes that affect sexual orientation that is not useful.  As I understand it there has been little research that has supported sexual orientation changing substantially.  I would not be surprised if the sexual orientation that a person reports could change over time.  Their are many factors that affect what orientation someone may report, including religious and soliologic factors.  What they report is not necessarily the same as what orientation they are. It is likely that it is primarily determined by genetics, and then influenced by the environment somewhat during maturation and to a lesser degree after maturation.  ::Whatever we feel about it isn't really important.  I understand that there are advocates of both views, and researchers who have research of some kind or another that indicates both.  I think it is fair that the article represent all viewpoints that can be documented using reliable sources.  I think it is wise to keep those viewpoints distinct from one another though, and not in the same paragraph.
