They are not being singled out. No way.
Our preachers preach on all manner of sin.
They seldom preach about homosexuality to be honest because it would be like preaching to the choir. A waste of time in our church.
The reason they do get as much attention as they do from religion in general is because they are trying to force the approval of their lifestyle on the nation in general especially Christians.
The United Methodists(liberal church) are on the verge of a split because of the issues of gay leadership and approval of ssm.
They are at great odds over those issues.
I think the Episcopalians and Anglicans have already split over one of the Episcopalian churches ordaining an openly gay man living in adultery with another man while still married to his wife, as a Bishop.
Gene Robinson was his name i believe.
