The author does seem to be sincere in his advice. However, he's misguided in a couple of things. First, he seems to believe that homosexuality is a psychological disorder. He even quotes older editions of the DSM. But everyone knows that the APA made the decision in the 1970s to no longer list homosexuality as a psychological disorder.
Also, I was really confused at the beginning of this book because he uses "gender identity" as a synonym for "sexual orientation". Furthermore, he believes that homosexuals suffer from GID (Gender Identity Disorder). Gender identity is 101% different from sexual orientation; not all homosexuals have GID, and not everyone with GID is homosexual.
The research that Mr. Haley offers is, for the most part, outdated. I saw where some of his sources where from as early as the 1950s. Was there nothing more recent to back his claims?
Some of his advice was just plain silly. Like when he was giving advice about how to prevent homosexuality in your sons, he basically says that little boys should shower with their dad! Umm, do I need to say anything further? However, he does not say that little girls should shower with their mothers. We call that a double standard.
I also didn't like how he presented homosexuality. He made it look like the worst thing in the world. He also seems to think that all male homosexuals are feminine and all lesbians are butch. And he makes it sound like "the horrible gays are out to get us!"
So, overall, I'm sorry I waisted my money on this book (I did read the sample first, but I was still curious). Although some parts were amusing. I gave this book 2 stars only because some parts amused me and Mr. Haley does seem sincere.
