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 isnt 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
