(LiveScience) Same-sex marriage has been rapidly gaining support in the United States, and yet Americans have been divided for the last decade on whether they think people can be born gay, a new Gallup poll shows.
Forty-two percent of Americans say people can be born gay, down slightly from 2013, when 47 percent said the same, the survey found. Meanwhile, more than a third of Americans (37 percent) attribute homosexuality to external factors, such as a person's upbringing and environment.
