Asked about whether homosexuality was a sin, initially, his only reply was 'we're all sinners' and now a resignation which specifically cites his Christian beliefs and the problems with reconciling them to his position politically as reasons for quitting.
The consequences of the focus on my faith is that I have found myself torn between living as a faithful Christian and serving as a political leader.

There are Christians in politics who take the view that they should impose the tenets of faith on society, but I have not taken that approach because I disagree with it - it’s not liberal and it is counterproductive when it comes to advancing the gospel.

To be a political leader - especially of a progressive, liberal party in 2017 - and to live as a committed Christian, to hold faithfully to the Bible’s teaching, has felt impossible for me.

It's not hard to see the over arching narrative there and if he considers homosexuality a sin then I'd say that's bigotry, to judge people as morally faulted or failed for their sexual orientation.
