Pro to the question "Is Sexual Orientation Determined at Birth?"
"Homosexuality is normal in a biological sense, that it is a distinctive beneficial behavior that evolved as an important element in human social organization. Homosexuals may be the genetic carriers of some of mankind's rare altruistic impulses."
Experts PhD's in psychology, without significant post-doctorate involvement in human sexuality issues, and PhD's in fields other than psychology, and MA's with significant post-graduate involvement in human sexuality issues. [Note: Experts definition varies by site.]
