Re Richard Teerlink's letter of June 20 ("Born gay," Forum):
One line in the Old Testament Book of Leviticus is the only source of knowledge that anti-gay bigots adhere to. I would urge people to study a little more science to become truly moral in their regard toward those who are different.
A 2008 study by Brendan Zeitsch of the Queensland Institute of Medical Research concluded, "There is considerable evidence that human sexual orientation is genetically influenced." In Scientific American Mind, scientist Emily V. Driscoll stated that homosexual and bisexual behavior is quite common in several species and that it fosters bonding: The more homosexuality, the more peaceful the species.
