From his initial hesitation to support same-sex marriage to his public conversion on the issue in 2012, and finally to national marriage equality today and the fight for trans rights that continues, the Out Magazine interview gives a great look into Obamas thoughts on the issue.
Among some of the topics discussed was his earliest exposure to someone in the LGBTQ community. Obama spoke of Dr. Lawrence Goldyn, a college professor he had, who stood out the most:
I was probably 18 years old — Lawrence was one of the younger professors — and we became good friends. He went out of his way to advise lesbian, gay, and transgender students at Occidental, and keep in mind, this was 1978. That took a lot of courage, a lot of confidence in who you are and what you stand for. I got to recognize Lawrence last year at our Pride Month reception at the White House, and thank him for influencing the way I think about so many of these issues.
