In commonality with all monastic faiths, Islam is opposed to same sex marriage. As part of the recent debate on this issue I supported the Coalition for Marriage https://en.wikipedia.org/wiki/Coalition_for_Marriage
It was a vigorously argued debate with opposing views on all sides. The matter was settled on the side of same sex marriages, and this is something which we all must accept.
People of a different sexual persuasion are no less human than the rest of us. Islam teaches is to be tolerant and accepting of all people, regardless of their faiths, backgrounds or sexual orientation.
A few years ago I was part of Channel Four series called “Make me a Muslim” in which I shared many engaging conversations with Luke, a young gay man. You could see this on You Tube ******
