 Your citation: 
 *"For example, they are supportive of an idea developed by Daryl Bem that children are aroused by peers who are different from them (in play, for instance) and that this arousal eventually leads to formation of erotic attraction and sexual orientation. Their argument that the play interests of children are directed by the prenatal hormonal environment serves as an explanation of how earlier events can influence later development. Jack Drescher (1) described this approach as emphasizing a possibly pathological early event (such as alteration in prenatal steroid exposure) with a subsequent inevitable developmental pathway that is not itself pathological."  

 The "subsequent inevitable developmental pathway" refers to the childhood experiences not the cause thereof. And the American Psychological Association clearly states on their homosexuality FAQ that the nurture debate has been discredited: "It is also important to realize that a parent's sexual orientation does not dictate his or her children's." and "considerable recent evidence to suggest that biology, including genetic or inborn hormonal factors, play a significant role in a person's sexuality." Perhaps your understanding of the subject is outdated?
