Religious individuals and organizations have been important in the fight against legalization of gay marriage, for example. But there are non-religious economic, social, and cultural arguments against gay marriage as well. In order to propagandize for gay marriage, leftist media deliberately portrays the opposition as limited to religious right "extremists."
But in every state in which the issue of gay marriage has been put on the ballot in some form or another, it has been defeated soundly. If a solid majority of voters are opposed, it intuitively means that there are many opposed who are not generally considered part of the "religious right." The movement against the homosexual agenda is not monolithic.
Of course. But to me, as a religious man, the issue is not that of socioeconomic expediency, but of deliberate destruction of human dignity and freedom inherent in the homosexual agenda. My objection is not economic, but anthropological.
