MLK claimed the church should be a headlight of society, not a taillight. It more often is a taillight as it wants to be safe. Post factum rather than ante factum.
When religious institutions accept people for who they are and how they wish to live a life they didn't ask for, they are Johnny-come-latelys to humanity.  Rather than leading acceptance of who people are, they come, belatedly,  after the fact, when things become socially accepted. 
In the meantime, people are making their own life decisions, not waiting for an official blessing.
