One thing that needs to be realized is that we are dealing with an issue set forth by Fundamentalist Christians which are a minority of all those who self identify as Christian. Liberal Christians, their Bible notwithstanding, have no dog in this fight. Many of them support Gay rights and some even have Gay clergy.
We are doing the Fundamentalist a favor by calling them "Christians" as if they represent the others who are in the 85% of the US Christian population. Fundamentalists despise them (in private) and refer to them as not "the right type of Christian". They should be referred to as Fundamentalist Christians by everybody else in order to emphasize that they are a minority in this nation. That will dull some of their self righteous halo.
