I actually think the ideal situation can happen. It all depends on the leaders. We need people to stop taking extremes on both sides of the issue and come together in the middle.
I think if you look at the gay marriage laws that have been proposed, passed, or voted down, you will see that one side has consistently been extreme, and the other side has consistently been moderate and reasonable.
You would do well to remember the paranoid ramblings that LDS leaders offered as arguments against civil rights and desegregation, such as
a speech delivered by Mark E. Peterson at Brigham Young University in 1954 (admittedly the documents are shown on an anti-mormon site, but the existence and contents of the speech are not disputed AFAIK):
"It is a good thing to understand exactly what the negro has in mind on this subject ... I would like to talk first of all about the negro and his civil rights.
...
I think I have read enough to give you an idea of what the Negro is after. He is not just seeking the opportunity of sitting down in a cafe where white people sit. He isn't just trying to ride on the same streetcar or the same Pullman car with white people. From this and other interviews I have read, it appears that the Negro seeks absorption with the white race. He will not be satisfied until he achieves it by intermarriage. That is his objective and we must face it. We must not allow our feelings to carry us away, nor must we feel so sorry for Negroes that we will open our arms and embrace them with everything we have."
So back then, as today, the civil rights movement was portrayed by the religious right as sinister and extreme, trying to impose its will on our way of life. You see, what "the Negro"
really wants is to force his blackness into our pure, delightsome white race.
That despicable lie was useful for opposing equal rights for blacks. The same despicable lie is being used today: "the gay" doesn't really want equality, he
really wants to force his gayness into our churches. Therefore, we must oppose moderate, reasonable proposals for LGBT equality.
