"...the reasons that people are leaving the church...."

But people are leaving all churches -- whether they have gay or straight clergy, married or celibate clergy, actively gay pastors with partners or single pastors, etc. My Lord, in UK this summer and the Anglicans church which allows nearly everything has dropped to 18% (or people who wish to identify as Anglican) and the Southern Baptists continue to drop in our country. 

The future of all churches need to raise serious questions, questions one could fill a hundred post with.
