John Dehlin is a practicing Mormon … and an outspoken activist for LGBTQ rights. In this touching talk at TEDxUSU, John shares how a friendship with an openly gay coworker changed his views on homosexuality and led him to a career in psychology.

In his research, John looks at the complex, often-prickly relationship between religion and sexuality. Here, he shares some of his findings — heartbreaking statistics about how negative feelings toward sexuality and attempts to “fix” same-sex attraction inspire suicides and teen homelessness.
