An article on MSNBC discusses a study which seeks genetic roots of homosexuality. This is a "federally funded study, led by Chicago area researchers" using 1,000 pairs of gay brothers.
The most notable quote is from the lead researcher of the new study, Dr. Alan Sanders of Evanston Northwestern Healthcare Research Institute. "It is more likely there are several genes that interact with nongenetic factors, including psychological and social influences, to determine sexual orientation."
So even the lead researcher believes that nature and nurture are both involved with developing one's sexuality!
However, it is unfortunate that the reporter misrepresented Exodus as "a Christian group that believes homosexuals can become straight through prayer and counseling." No where does Exodus ever make such a claim but the easiest way for gay-advocates to fight is to misrepresent the facts.
